Umbhali inkolelo-mbono yokuziphendukela isakhiwo organic compounds. Imfundiso yokuziphendukela isakhiwo organic compounds A. M. Butlerova

Chemistry - isayensi ukuthi usinika lonke ezihlukahlukene izinto futhi izinto zasekhaya, okuyinto thina akazange anqikaze oyisebenzisa nsuku zonke. Kodwa ukuza kuvulwa ezihlukahlukene ezifana compounds, okuyinto namuhla eyaziwa, osokhemisi eziningi okwadingeka abhekane nakho ngendlela eziyinkimbinkimbi zesayensi.

Kunomsebenzi omningi, ucwaningo eziningi eziyimpumelelo futhi akuphumelelanga, cwe theory nolwazi base - konke lokhu kwaholela ekumisweni ezindaweni ezahlukene yokuthakwa kwamakhemikhali zezimboni ukuvumele synthesize futhi asebenzise ngezinto zokwakha zesimanje: iraba, epulasitikini, epulasitikini, inhlaka, Alloys, izibuko ahlukahlukene, silicones, nokunye.

Omunye futhi elalidume kunawo wonke, osokhemisi ahlonishwe, owenza banikela ngendlela ebalulekile ekuthuthukiseni yokuthakwa kwamakhemikhali organic kwaba abantu Russian Butlerov AM imisebenzi yakhe, izimpumelelo Imiphumela yomsebenzi sicabanga kafushane kulesi sihloko.

i-curriculum vitae

Usuku lokuzalwa usosayensi - ngo-September 1828, inani emithonjeni ehlukene akuyona iyunifomu. Wayeyindodana ka uLieutenant Colonel Michael Butlerova ezilahlekelwe umama kusenesikhathi. Zonke ebuntwaneni wahlala on ifa lomndeni kakhokho wakhe edolobhaneni Podlesnaya Shentala (manje Republic of endaweni Tatarstan).

Watadisha ezindaweni ezihlukene, okokuqala isikole avaliwe kuyimfihlo, bese ubuye esikoleni esiphakeme. Kamuva, wangena University of Kazan eMnyangweni physics kanye mathematics. Nokho, naphezu kwalokhu nesithakazelo kakhulu kwamakhemikhali. Umbhali esizayo inkolelo-mbono yokuziphendukela isakhiwo organic compounds okusalayo ngemuva iziqu esikhundleni njengoba uthisha.

1851 - lokuvikeleka kwezifiso ezisemqoka ezingumphumela mqondo wokuqala ezifundweni ku "Ukulumbanisa nge-oksijini of organic compounds". Ngemva kombukiso brilliant wanikwa ithuba ukuphatha wonke amakhemikhali nokusebenzelana kwawo eyunivesithi.

Umbhali inkolelo-mbono yokuziphendukela isakhiwo organic compounds kwaba isitebhisi eside umsebenzi futhi 1874 waba omunye okungcono izifundiswa Petersburg Academy of Sciences.

Usosayensi wafa ngo-1886, lapho afike achitha khona esengumntwana e ifa lomndeni kakhokho wakhe. Ngo umndeni yesonto zendawo wangcwatshwa.

umnikelo Usosayensi sika ekuthuthukiseni ulwazi zamakhemikhali

Imfundiso yokuziphendukela isakhiwo organic compounds Butlerov - ngokuqinisekile umsebenzi wakhe oyinhloko. Nokho, hhayi oyedwa kuphela. Wayekhipha yona le usosayensi idale isikole sokuqala Russian of bamakhemikhali.

Futhi kusukela izindonga zawo zazilotshiwe ososayensi enjalo, kamuva ababenolwazi isisindo omkhulu kakhulu ekuthuthukeni wonke yesayensi. Laba ngabantu ezilandelayo:

• Markovnikov;
• onogwaja;
• Kondakov;
• iThabori;
• Konovalov;
• Lions nabanye.

Umbhali inkolelo-mbono yokuziphendukela isakhiwo organic compounds idale eziningi imisebenzi ku ngesayensi yemvelo, kuhlanganise ne-chemistry. Ikakhulukazi bacwaninga iye enikelwe ke organic compounds.

Umsebenzi kwamakhemikhali organic

Leyo misebenzi kungenziwa ngokuthi okuningi. Ngemva Butlerof cishe ngaso sonke isikhathi khulula ayichitha yakhe laboratory inyuvesi, enifeza ucwaningo ehlukahlukene, okwenza okutholakele futhi kufinyelelwe iziphetho ezinembile. Vele ngakho-ke wazalwa imfundiso yokuziphendukela chemical isakhiwo organic compounds.

Kukhona ezinye umsebenzi ikakhulukazi kakhulu usosayensi:

• idaliwe umbiko we inkomfa ngesihloko esithi "Ngo isakhiwo amakhemikhali ndaba";
• umsebenzi ocwaningeni "On the amafutha abalulekile ';
• imisebenzi yesayensi lokuqala "I namachibi of organic compounds".

Ngaphambi okubekwe ngayo yayo kanye kudalwa umbhali inkolelo-mbono yokuziphendukela isakhiwo organic compounds isikhathi eside ukutadisha umsebenzi kwabanye ososayensi ezivela emazweni ahlukahlukene, ngafundela imisebenzi yabo, kuhlanganise umshayeli. Kungaleso sikhathi kuphela lapho, ukuze kuvame futhi nokumisa ulwazi aluthola, wayebonisa zonke iziphetho ngokuya theory yayo bokuzisholo.

Imfundiso yokuziphendukela isakhiwo organic compounds A. M. Butlerova

XIX leminyaka kuphawulwa ukuthuthukiswa ngokushesha cishe yonke imikhakha yesayensi, kuhlanganise ne-chemistry. Ikakhulukazi, qhubeka buthelela okutholakele enkulu carbon futhi compounds yayo, izinto eziphilayo kuthinte ngekwehlukahlukana kwalo. Kodwa akekho ongalokotha ukuhlela bese uhlela zonke le nto letinemaciniso, kuholele zifana futhi ukukhomba amaphethini ajwayelekile, lapho konke yakhiwe.

Eyokuqala senziwa Butlerov A. M. Ukuthi theory okhazimulayo isakhiwo amakhemikhali organic compounds, izihlinzeko eyathi mass engqungqutheleni laseJalimane bamakhemikhali. Lokhu kwaba ukuqala kwenkathi entsha ekuthuthukiseni isayensi, i-chemistry organic waqhamuka indlela yentuthuko enkulu.

Usosayensi waya kuwo kancane kancane. Wachitha eziningi ucwaningo futhi wabikezela ukuba khona izinto nge izakhiwo elinqunyiwe, wathola uhlobo oluthile ukusabela, futhi wabona ngemuva kwazo esikhathini esizayo. Abaningi watadisha imisebenzi ozakwabo kanye abakutholile. Kuphela ngokumelene lokhu ngokuhlela umsebenzi ngokucophelela futhi onzima esafuna wakwazi ukwakha wobuciko yakhe. Futhi manje, imfundiso yokuziphendukela isakhiwo organic compounds kule Chemistry kwesigaba - cishe iyafana ukuthi kohlelo ngezikhathi wezinto ezingaphili.

Ukuvula usosayensi othile ngaphambi kokudalwa imfundiso yokuziphendukela

Yini okutholakele benziwa futhi banikezwe theory ukulungisiswa isazi ngaphambi kwakukhona imfundiso yokuziphendukela isakhiwo organic compounds A. M. Butlerova?

1. ubuhlakani Domestic lokuqala kwemiqondo izinto eziphilayo ezifana methenamine, formaldehyde methylene iodide nabanye.
2. Umqondo kusuka impahla ushukela-wezinto ezingaphili (utshwala ephakeme), kanjalo okubangela igalelo eduze vitalism theory.
3. Wabikezela ngokuzayo polymerization ukusabela, ebabizela okungcono, njalo ethembisa.
4. Isomerism kwachazwa okokuqala kubo kuphela.

Yiqiniso, lokhu-mlando ezinkulu yomsebenzi wakhe kuphela. Empeleni, eminyakeni eminingi umsebenzi onzima lingachazwa nge usosayensi othile isikhathi eside. Nokho, esiphawuleka kunazo zonke namuhla isibe zonke theory efanayo isakhiwo organic compounds, okuyinto nekubeka bese ukhuluma olunye.

Endaweni yokuqala imfundiso yokuziphendukela

Ngo-1861, usosayensi omkhulu Russian kulowo mhlangano ka bamakhemikhali emzini Speyer ukwabelana nozakwethu imibono yabo isakhiwo yezimbangela nokwehluka organic compounds avete konke lokhu ngesimo le mfundiso.

Into yokuqala okulandelayo: bonke ama-athomu ngaphakathi molecule axhunyiwe ngokulandelana, it is kunqunywa valency yabo. Uma le-carbon-athomu ziphephile inkomba Valence elilingana ezine. Oxygen inenani lokhu inkomba ilingana ezimbili, i-hydrogen - ubunye.

Wasikisela isici efanayo nalena ebizwa ngokuthi chemical isakhiwo ketshezi. Kamuva uqoke izinkulumo zakhe zithathwe ephepheni amafomula ingcaca umnyuziki kwesakhiwo, wafingqa futhi yamangqamuzana ezinto eziphilayo.

Lokhu kubuye lo mkhuba izinhlayiya carbon axhumene i chain engapheli isakhiwo ehlukene (lwento, eyindilinga, branched).

Ngokuvamile, imfundiso yokuziphendukela isakhiwo organic compounds Butlerova isikhundla yayo yokuqala echaziwe ukubaluleka valency kanye ifomula olubumbene kwakwakhe ngayinye, izakhiwo sibonakalisa nokuziphatha efana ngesikhathi ukusabela.

Eyesibili isikhundla kwemfundiso yokuziphendukela

Kuleli qophelo kwachazwa ukuhlukahluka organic compounds emhlabeni. Kususelwa uxhumano carbons esikuziphathimandla, usosayensi wasikisela ukuthi emhlabeni kukhona compounds ezihluke kokuba izakhiwo ezahlukene, kodwa liyefana ngokuphelele Ukwakheka yamangqamuzana ezinto eziphilayo. Ngamanye amazwi, kukhona lo mkhuba isomerism.

Lo mbono ukuhlinzekwa isakhiwo organic compounds A. M. Butlerova hhayi kuphela wachaza okushiwo isomers, futhi isomers, kodwa futhi usosayensi esisebenzayo okungenakuqhathaniswa okutholwa yibo bonke baqinisekisa.

Ngokwesibonelo, lapho kuhlelwe butane isomer - isobutane. Khona-ke, pentane kwabikezelwa ukuthi zikhona has hhayi elilodwa ezintathu isomers, esekelwe isakhiwo kwakwakhe. Futhi synthesize kubo bonke, okufakazela ukuthi akanacala.

Ukudalulwa isikhundla yesithathu

Into elandelayo theory uthi zonke athomu nezinhlayiyana ezincane ngaphakathi kwakwakhe efanayo kungathinta property nomunye. Kule futhi kuzoncika ukuziphatha ketshezi izinhlobo ezahlukene ukusabela, owabonakaliswa zamakhemikhali nezinye izakhiwo.

Ngakho, ngaphansi kwaleli lungiselelo ukuhlonza eziningana ekilasini elinabafundi organic compounds zehlukene ukubukeka nokwakheka ngokuchaza iqembu sokusebenza.

Imfundiso yokuziphendukela isakhiwo organic compounds A. M. Butlerova ngokufingqiwe cishe zonke izincwadi ku-chemistry organic. Phela, kuyinto - ngesisekelo lesi sigaba, incazelo yokuthi yonke imithetho, ezakhiwe-molecule.

Inani imfundiso yesimanje

Yiqiniso, inkulu. Lo mbono wenza kwenzeka:

1. ukuhlanganisa futhi ahlele zonke izinto oluyiqiniso zanqwabelana ngesikhathi indalo yayo;
2. achaze uhlaka lwamaphethini, izakhiwo zezakhi ezihlukahlukene;
3. ukunikeza incazelo egcwele yezizathu ezihlukahlukene ezifana enkulu compounds kwamakhemikhali;
4. Wanikeza kuqale ngoba syntheses eziningi izinto ezintsha, ezisuselwa amalungiselelo kwemfundiso yokuziphendukela;
5. ukuba azihambele ukubukwa, ukuthuthukisa ocatshangelwayo-athomu-yamangqamuzana ezinto eziphilayo.

Ngakho-ke, uma sithi umbhali inkolelo-mbono yokuziphendukela isakhiwo organic compounds, isithombe ongawabona ngezansi, wenza lukhulu - alisho lutho. Butlerova Kungashiwo kufanele kubhekwe umsunguli wesayensi yokuthakwa kwamakhemikhali organic, umsunguli izisekelo zalo theory.

umbono wayo yesayensi zomhlaba, wayeyisazi ukucabanga, ikhono landulele yi waba nendima ngokuhamba kwesikhathi. Le ndoda yayinemibuzo nekhono elikhulu emsebenzini, isineke njalo ukuzama, Kuhlanganisa, abaqeqeshiwe. Engalungile, kodwa ngaso sonke isikhathi ukufunda izifundo wenze ilungelo eside iziphetho.

Kuphela iqoqo okunjalo izimfanelo acumen ibhizinisi, ukuphikelela bavunyelwe sifinyelele nomphumela ofiselekayo.

Lolu cwaningo yokuthakwa kwamakhemikhali organic esikoleni

Ngokuhamba imfundo yesibili kulolu cwaningo elisekela organic unikezwa isikhathi hhayi okungaka. eyodwa kwezine kuphela grade 9 futhi ngonyaka esigcwele 10 ezingeni (uhlelo Gabrielyan OS). Nokho, ngalesi sikhathi kwanele ukuthi izingane bakwazi ukuhlola wonke amakilasi eyinhloko compounds, ikakhulukazi isakhiwo sabo futhi ngesilwane esifuywayo, ukubaluleka esisebenzayo.

Isisekelo ekuqaleni Yiqiniso - imfundiso yokuziphendukela isakhiwo organic compounds A. M. Butlerova. Kwebanga le-10 abazinikezele ukucabangela egcwele izikhundla zawo, futhi kamuva - isiqinisekiso theory ne practical ekuhloleni ekilasini izidakamizwa ngamunye.
