Tam sim no kaw lub qhov cua kom tiav. Unsaturated hydrocarbons zoo li ethyl, tseem hu ua acetylene, hlawv ua kom daj, sooty nplaim taws vim tsis tiav combustion nyob rau hauv cov huab cua. Cov nplaim taws yog sooty vim tias feem pua ntawm cov pa roj carbon sib piv siab dua li ntawm alkanes thiab lwm yam ua tsis tau oxidized kiag li hauv huab cua.

Ua raws li qhov kev pom no, vim li cas cov saturated hydrocarbons hlawv nrog lub nplaim xiav?

Ans. Saturated hydrocarbons muaj cov ntsiab lus carbon tsawg, yog li muaj kev sib xyaw ua tiav ntawm cov tebchaw no thiab yog li, cov ntsiab lus no hlawv nrog nplaim xiav . Yog li cas unsaturated hydrocarbons , vim lawv cov ntsiab lus carbon siab thiab cov ntsiab lus hydrogen tsawg, muaj kev sib txuas tsis tiav.

Kuj Paub, yog vim li cas cov cawv hlawv nrog nplaim taws huv si? ⚛ Cawv combusts ( kub hnyiab ) nrog haus luam yeeb los yog sooty nplaim taws vim kev tsim cov khoom carbon. Combustion ntawm cawv tso tawm lub zog ua cawv pab tau li roj.

Ntxiv mus, vim li cas alkanes hlawv nrog nplaim taws?

Alkanes muaj tsawg cov ntsiab lus ntawm cov pa roj carbon monoxide nyob rau hauv lawv.. nrog txaus oxygen tag nrho yuav hlawv huv si. Alkanes cov mis mos yog CnH(2n+2). Qhov siab dua cov pa roj carbon ntau hauv hydrocarbon, cov pa oxygen ntau dua thiab cua sov yuav tsum hloov tag nrho cov pa roj carbon monoxide rau CO2. Yog vim li cas alkanes feem ntau hlawv nrog nplaim taws huv si.

Vim li cas alkenes hlawv nrog nplaim taws?

Zoo li cov alkanes, cov alkenes raug combustion. Txawm li cas los xij, alkens yog tsawg dua yuav combust kiag li, yog li lawv nyiam hlawv hauv av a nplaim taws vim tsis tiav combustion.
