Nyob rau hauv cov ntaub ntawv ntawm benzaldehyde, vim cov carbonyl carbon txuas rau lub nplhaib benzene muaj qhov txo qis hauv polarity. … Yog li cov carbonyl carbon ntawm benzaldehyde yog electrophilic tsawg dua carbonyl carbon nyob rau hauv propanal. Qhov no yog vim li cas Propanal reactive dua Benzaldehyde.
Yuav ua li cas ntau reactive benzaldehyde los yog propanal?
Cov pa roj carbon atom ntawm pawg carbonyl ntawm benzaldehyde yog electrophilic tsawg dua carbon atom ntawm pawg carbonyl tam sim no nyob rau hauv propanal. Lub polarity ntawm carbonylgroup yog txo nyob rau hauv benzaldehyde vim resonance raws li qhia hauv qab no thiab yog li nws tsis tshua muaj reactive tshaj propanal.
Vim li cas benzaldehyde thiaj li muaj zog?
Vim qhov loj thiab loj loj ntawm pawg phenyl, steric hindrance tshwm sim los ntawm benzaldehyde yog ntau tshaj acetaldehyde. … Yog li ntawd, lub xub ntiag ntawm electron pub pab pawg txo cov nucleophilic ntxiv cov tshuaj tiv thaiv. Li no, qhov kev txiav txim ntawm reactivity ntawm tag nrho cov tebchaw yogCH3CHOC6H5CHOCH3COCH3C6H5COC6H5.
YPuas yog benzaldehyde reactive dua phenol?
Phenol yog ntau reactive dua benzene rau electrophilic hloov cov tshuaj tiv thaiv.
Puas benzaldehyde electron pub lossis rho tawm?
Siv benzaldehyde ua piv txwv (cov pab pawg carbonyl yog electron thim), nws tuaj yeem pom tias tam sim no resonance tso cov nqi zoo hauv lub nplhaib. …Thaum ibEWG tam sim no, tus nqi zoo kuj tseem tsis tau nyob ntawm txoj haujlwm meta, tab sis tsuas yog cov ortho- thiab para- txoj haujlwm.
