Question

P-Nitrotoluene on future nitration gives

Answer 1

Correct option (a)

Position 2 is favoured by --CH₃ (o, p-directing group) as well as -NO₂ group (m-directing group).

Answer 2

(a)

Nitration of p-nitrotoluence gives almost exclusively 2,4-dinitrotoluene because both −CH3 and −NO2 groups direct the incoming electrophile −+NO2 to the same C atom.
