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.

Puas yog cyclic hydrocarbons saturated los yog unsaturated?
Lub cyclic hydrocarbon yog hydrocarbon nyob rau hauv uas cov carbon saw txuas mus rau nws tus kheej hauv ib lub nplhaib. Lub cycloalkane yog cyclic hydrocarbon nyob rau hauv uas tag nrho cov carbon-carbon bonds yog ib daim ntawv cog lus. Ib yam li lwm cov alkanes, cycloalkanes yog cov khoom sib xyaw saturated
Vim li cas cov hluav taws xob sab nraud tsuas yog suav nrog hauv daim duab kos duab hluav taws xob?
Atoms nrog 5 los yog ntau tshaj valence electrons tau electrons tsim ib tug tsis zoo ion, los yog anion. Vim li cas thiaj li cov hluav taws xob sab nraud tsuas yog cov uas suav nrog hauv daim duab orbital filling? lawv tsuas yog cov uas koom nrog cov tshuaj tiv thaiv thiab kev sib raug zoo. 2s orbital nyob deb ntawm lub nucleus txhais tau tias nws muaj zog ntau dua
Vim li cas nws nyuaj rau txheeb xyuas cov hlau ions los ntawm Xim ntawm nplaim taws?
Lub zog no raug tso tawm raws li lub teeb, nrog cov yam ntxwv nplaim xim ntawm cov hlau ions sib txawv vim qhov sib txawv ntawm cov hluav taws xob hloov pauv. Raws li tau hais, cov kev sim no ua haujlwm zoo dua rau qee cov hlau ions dua li lwm yam; tshwj xeeb, cov ions pom nyob rau hauv kab hauv qab ntawm cov infographic feem ntau yog faus thiab nyuaj rau qhov txawv
Vim li cas alkanes hlawv nrog nplaim taws xiav?
Alkane kub hnyiab nrog cov nplaim xiav los yog huv si vim tsis tiav combustion ntawm saturated hydrocarbon hauv huab cua
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
