Assertion (A) Phenols give o-and p-nitrophenol on nitration with conc. HNO_(3) and H_(2)SO_(4) mixture. Reason (R) -OH group in phenol is o-,p-directing.

Phenol on heating with NaNO_(2) and a few drops of conc. H_(2) SO_(4) gives :

Conc. H_(2)SO_(4) is not

Phenol when nitrated with conc. HNO_(3) in presence of conc. H_(2)SO_(4) forms

Assertion (A): Phenol on nitration with Conc. HNO_(3) and H_(2)SO_(4) give a mixture of o and p-nitro phenol. Reason (R): -OH group is deactivating group.
