Nyob rau hauv ntau cov qauv resonance resonance qauv Hauv chemistry, resonance, tseem hu ua mesomerism, yog ib txoj hauv kev piav qhia txog kev sib koom ua ke hauv qee cov molecules lossis ions los ntawm kev sib xyaw ntawm ntau cov qauv tsim(los yog cov ntaub ntawv, kuj muaj ntau yam hu ua resonance structures lossis canonical structures) rau hauv resonance hybrid (los yog hybrid qauv) hauv valence bond theory. https://en.wikipedia.org › wiki › Resonance_(chemistry)
Resonance (chemistry) - Wikipedia
rau azulene, cov neeg koom siab ruaj khov tshaj plaws muab tus nqi tsis zoo hauv 5-tus neeg koom nrog lub nplhaib thiab tus nqi zoo hauv 7-tus tswv cuab lub nplhaib. … Qhov kev sib cais ntawm qhov zoo thiab qhov tsis zoo no ua rau lub molecule lub sijhawm dipole ntawm 1.08 D.
Vim li cas azulene thiaj li polar?
[5] (a) Azulene yog ib qho polar molecule vim nws muaj kev koom tes tseem ceeb los ntawm cov qauv resonance nyob rau hauv uas ob lub nplhaib tuaj yeem sawv cev ua ib qho aromatic ion Piv txwv li, xya -membered nplhaib yog ib qho aromatic cation nyob rau hauv A, thiab tsib-membered nplhaib yog ib qho aromatic anion nyob rau hauv B.
YPuas azulene muaj dipole?
Azulene feem ntau yog saib los ntawm kev sib xyaw ntawm cyclopentadiene thiab cycloheptatriene rings. Zoo li naphthalene thiab cyclodecapentaene, nws yog 10 pi electron system. … Nws lub sijhawm dipole yog 1.08 D, sib piv nrog naphthalene, uas muaj lub sijhawm dipole ntawm xoom.
YPuas yog azulene polar lossis nonpolar?
Azulene muaj qhov tseem ceeb polarity, nrog tsib lub nplhaib tsis zoo thiab xya lub nplhaib zoo.
Vim li cas azulene yog cov qauv zoo resonance?
Lub xub ntiag ntawm sp2hybridized carbon atoms yooj yim rau delocalization ntawm electrons. Qhov no delocalisation ntawm electrons ces ua rau ntau yam resonance qauv ntawm azulene.
