Cov suav delocalization zog rau benzene yog qhov sib txawv ntawm cov khoom no, los yog (6α+8β)−(6α+6β)=2β. Uas yog hais tias, lub laij lej delocalization zog yog qhov txawv ntawm lub zog ntawm benzene nrog tag nrho π bonding thiab lub zog ntawm 1, 3, 5-cyclohexatriene nrog alternating ib leeg thiab ob daim ntawv cog lus.
Yuav ua li cas koj xam delocalization zog?
Lub zog delocalization yog txhais raws li: lub p electron zog ntawm lub cev rho tawm p electron zog ntawm ib qho sib npaug ntawm cov nyiaj rho tawm ob npaug.
Dab tsi yog lub zog delocalisation ntawm benzene?
Qhov tsis zoo. Hauv qhov tseeb, lub nplhaib benzene tso tawm lub zog tsawg dua uas txhais tau tias nws ruaj khov dua. Lub zog sib txawv ntawm lub zog hloov pauv ntawm lub zog kwv yees thiab lub zog siv tau yog149 kJ / mol. Lub zog no hu ua delocalisation zog.
Koj ua li cas xam lub zog resonance ntawm benzene?
Lawv muab 977 kcal rau lub tshav kub ntawm atomization ntawm Kekul6 siv qauv: Qaoo (Kekul6)=3 X 56 + 3 X 95.2 + 6 X 87.3=977 kcal. Lub zog resonance ntawm benzene raws li cov qauv siv no yog vim li no: QaoO(ac- tual) -QaoO(KekuI6)=1039-977=62 kcal thiab tsis yog 39 kcal.
Delocalisation zog yog dab tsi?
Lub zog delocalization yog qhov kev ruaj ntseg ntxiv uas yog qhov sib xyaw ua ke ntawmmuaj delocalized electrons. Electron delocalization tseem hu ua resonance. Yog li ntawd, lub zog delocalization tseem hu ua resonance zog.
