Question

Benzene reacts with chlorine in the presence of an iron catalyst

Answer 1

Benzene reacts with chlorine or bromine in the presence of a catalyst, replacing one of the hydrogen atoms on the ring by a chlorine or bromine atom. The reactions happen at room temperature. The catalyst is either aluminium chloride (or aluminium bromide if you are reacting benzene with bromine) or iron.

Answer 2

Answer: This leads to the formation of chlorobenzene.

Explanation:

When benzene reacts with chlorine gas in the presence of iron catalyst such as iron (III) chloride $(FeCl_3)$, it displaces one hydrogen from the ring to chlorine atom and leads to the formation of chlorobenzene.

The chemical equation for the reaction of benzene with chlorine in the presence of iron catalyst follows:

$C_6H_6+Cl_2\xrightarrow[]{FeCl_3} C_6H_5Cl+HCl$

The image for the above reaction is attached below.

Hence, this leads to the formation of chlorobenzene.
