Answer 1

0 0 CI HNO3 H2SO4 A1Cl3 NO2 Zn(Hg), HCI Br2, FeBr3 Sn, HCl Br Br NH2 NO2 NO Explanati on: Reaction of benzene with acid chlori de and A1C13 produces acyl benzene as product. - COCH2CH3 group is an electron withdr awing group which withdraws ele ctrons and directs the incoming electrophile to meta position. Zn(Hg). HCl reduces -CO group to -CH2 group. alkyl group on benzene ring directs the incoming electrophile to para position. Sn, HCl reduces nitro group to -NH2 group.
