Assertion (A) : `Ph overset (o+)(N_2) Br^(Θ)` couples with `N, N`-dimethyl aniline (I) but not with ` 2,6,`-dimethyl-`N,N`-dimethuyl aniline (II)
Reason (R ): Due to steric inhibition of resonce , the p-potion of (II) is not sufficiently activated fro the coupling reation.
Due to steric inhibition of resonamne, the p-position of (II) is not sufficiently activated for the coupling reaction.
