WebNext, let's do an acid anhydride. So for an acid anhydride, the inductive effect is even more important. And if the inductive effect is even more important, so if we think about this oxygen here as being very electronegative, that means that we're gonna get an even higher value for K. So an even higher value for K, an even stronger carbonyl. WebFeb 27, 2016 · It is because the methyl group has a positive inductive effect; this effect is due to the higher electronagetivity of carbon than hydrogen, which attracts the electron …

Does phenyl show inductive effect? Phenyl ring is known to exert negative inductive effect but each phenyl ring in biphenyl (C_6H_5-C_6H_5) is more reactive than benzene towards electophilic substitution-Explain.

WebFeb 18, 2024 · see the link for the reasoning: Inductive effect of phenyl ring Also the allylic group would be donating via inductive effect, thus making the carboxylate ion unstable ( after acid donates H+ ions) But an sp2 carbon is more electronegative than an sp3 carbon, hence it will donate less. (more electronegative element tries to retain electrons) So 1 …
