Assertion (A) : Ph overset (o+) (N_2) Br^(Θ) is more acidic thanNH_4 Br. Reason (R ) : Ph overset (o+)(N)H_(3) (anilinum ion ) is resonance stabilinsed .

Answer»

If both (A) and (R ) ar TRUE, and (R ) is the CORRECT explanation of (A).
If both (A) and (R ) are true , and (R ) is not the correct explanation of (A).
If (A) is true , but (R ) is FALSE .
If both (A) and (R ) are false .

Solution :`NBH_2` is STRONGER base than aniline , therfore , the cojugate acid of aniline (i.e., `Ph overset (o+) (N) H_3)` is more acidic than the conjugate acid of `NH_3` (i.e, `overset (o+) (N) H_4` ion).
