Phenyl inductive effect
WebThis is because the inductive effect of the alkyl groups causes the electron-withdrawing groups to be more stable. The stability of a carbanion in benzene is due to the resonance effect of the benzene ring. The stability of a carbanion in an aromatic ring is because the electrons in the aromatic ring are delocalized. WebInductive effect is useful in explaining the strength of some organic acids and bases. a) Effect of substituent on the acid strength of aliphatic acids. ... Reason : due to –I effect of phenyl group. Applications of Inductive effect: Relative basic strength of amines 1. All aliphatic amines are more basic than ammonia.
