Benzene nplhaib : Ib aromatic functional pab pawg characterized los ntawm a nplhaib ntawm rau carbon atoms, sib txuas los ntawm kev sib txuas ib leeg thiab ob daim ntawv cog lus. A benzene nplhaib nrog asingle substituent hu ua a phenyl pawg (Ph).
Yog li ntawd, dab tsi yog pab pawg ua haujlwm tam sim no hauv benzene?
1 Teb. " Benzene " characterizes ib qho compound thiab tsis yog a pab pawg ua haujlwm , " Aromatic Hydrocarbon "tus yam ntxwv ntawm cov khoom sib txuas. Kuv xav hu koj cov qauv asa pab pawg ua haujlwm , "Phenyl".
Tom qab, lo lus nug yog, dab tsi yog ib pab pawg neeg aromatic functional? Nyob rau hauv cov organic chemistry, aromaticity yog ib yam khoom ntawm cyclic (ntiv nplhaib-shaped), planar (flat) cov qauv nrog lub nplhaib ntawm resonance bonds uas muab kev ruaj ntseg ntxiv piv rau lwm yam geometric lossis kev sib txuas nrog tib txheej ntawm atoms. Ib aromatic functional pab pawg lossis lwm yam hloov pauv hu ua anaryl pab pawg.
Kuj Paub, puas yog phenyl ib pab pawg ua haujlwm?
Phenyl yog a pab pawg ua haujlwm nrog lub nplhaib anaromatic bonded rau lwm tus pab pawg . Thiab, phenol yog amolecule uas yog ib qho xwb phenyl bonded rau ib hydroxyl pab pawg . Txawm li cas los xij, qee qhov chaw xav txog phenol nws tus kheej a pab pawg ua haujlwm.
Vim li cas benzene feem ntau sawv cev los ntawm hexagon nrog lub voj voog hauv nws?
Txhawm rau hais txog qhov resonance ntawm ob lub tsev Lewis, tshuaj benzene yog feem ntau sawv cev as a hexagon nrog lub voj voog nyob rau hauv nws . Qhov no qhia txog qhov tseeb tias C C ob daim ntawv cog lus tsis tuaj yeem raug xa mus rau cov npoo ntawm qhov tshwj xeeb hexagon . Liab lab ntawm cov organic tebchaw muaj rau-memberedrings yam ntxwv ntawm tshuaj benzene.

Dab tsi yog tag nrho geometry ntawm lub nplhaib benzene?
Lub nplhaib benzene muaj rau carbon atoms sib koom ua ke nyob rau hauv ib lub tiaj tiaj lossis lub nplhaib hexagon. Txhua cov pa roj carbon yog sib koom ua ke rau ib qho hydrogen vim yog peb qhov sib hloov ob daim ntawv cog lus. Qhov no qhia tau hais tias txhua cov pa roj carbon monoxide yog sib koom ua ke rau 3 lwm tus thiab ib lub pob txha ob leeg. Yog li cov molecular geometry ntawm txhua carbon yog trigonal planar
Dab tsi feem ntau yog pab pawg ua haujlwm thiab vim li cas cov pab pawg no tseem ceeb?
Cov pab pawg ua haujlwm tau txuas mus rau carbonbackbone ntawm cov organic molecules. Lawv txiav txim siab tus yam ntxwv thiab tshuaj lom neeg reactivity ntawm molecules. Cov pab pawg ua haujlwm tsis tshua muaj kev ruaj ntseg dua li cov pa roj carbon monoxide thiab zoo li yuav koom nrog cov tshuaj tiv thaiv
Lub organelle twg yog lub luag haujlwm rau lub zog tshuaj uas xav tau rau lub cell ua haujlwm?
Mitochondria Function Mitochondria feem ntau hu ua "powerhouses" lossis "zog factories" ntawm lub xovtooj vim tias lawv yog lub luag haujlwm rau kev ua adenosine triphosphate (ATP), lub xovtooj ntawm lub zog nqa lub cev
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
Dab tsi ua haujlwm pab pawg tseem ceeb tshaj plaws rau lub zog ntawm tes?
Nrog plaub lub electronegative oxygen atoms, phosphate pawg yog cov reactive heev, thiab kev hloov ntawm ib pab pawg phosphate los ntawm ib tug molecule mus rau lwm tus muab lub zog rau cov tshuaj tiv thaiv. ATP, lub luag haujlwm tseem ceeb hauv lub hlwb, yog tsim los ntawm peb pawg phosphate sib koom ua ke
