Question

write the reaction for the catalytic reduction of nitrobenezene follow by the reaction ofbproduct so formed with bromine water​

Answer 1

Answer:

Nitrobenzene reacts with Br2 in the presence of FeBr3 to give m-bromonitrobenzene as the major product.

Answer 2

The chemical reaction for the reduction of nitrobenzene followed by the reaction with bromine water is:

$C_{6} H_{5} NO_{2} + H^{+}$ → $C_{6} H_{5} NH_{2}$

$C_{6} H_{5} NO_{2} + Br_{2} .H_{2} O$ → $C_{6} H_{2} (Br)_{3} NH_{2}$

• Nitrobenzene undergoes catalytic reduction to yield an aromatic amine, aniline.

• Aniline on bromination yield a trisubstituted product, 2,4,5-tribromo aniline. This is an electrophilic substitution reaction.

• Amino group is an activating group and directs the incoming electrophile to the ortho and para positions.
