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 … Webto strong electron-withdrawing inductive effect, -I: Fig. 1 They also exhibit electron-withdrawing resonance effects, -Re: Thus, these groups make the aromatic ring very electron poor relative to benzene and, therefore, they strongly deactivate the ring i.e. reactions proceed much slower in rings bearing these groups compared
Chemists reconsider the impact of through-space effects
WebOct 10, 2024 · The phenyl group is said to be weakly activating, suggesting that it donates electrons to a benzene ring bonded to it. 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 … philippe christiane
