Question

Bromine gives substitution reaction products
with benzene readily in presence of :
(a) Sunlight
(b) Platinum
(c) FeBr₃ at 35°C
(d) FeBr₃ at high temperature

Answer 1

Answer:

the correct option is option d

Answer 2

(c) FeBr₃ at 35°C

Explanation:

Bromine gives substitution reaction products with benzene readily in presence of a catalyst, FeBr₃ at 35°C. Benzene reacts with chlorine or bromine in an electrophilic substitution reaction, but only in the presence of a catalyst. The catalyst is either aluminium chloride (or aluminium bromide if you are reacting benzene with bromine) or iron.

Option C is the answer.
