Assertion (A) : Ph overset (o+)(N2) Br^...

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.

Assertion (A): 2,6-Dimethyl-4-nitrophenol (I) is more acidic than 3,5-dimethyl-4-nitrophenol (II). Reason (R ): It is due to the steric inhibition of the resonance of (-NO_(2)) group with two (Me) groups in (II).

Assettion (A) : Coupling of Ph overset (o+) (N_2) Br^(Θ) with aniline is faster than with phenol. Reason (R ): Aniline is more overline e donating than phenol.

Assertion (A) : The ionisation energy of N is more than that of O Reason (R ) : Electronic configuration of N is more stable due to half - fillied 2p orbitals
