Answer:
Toluene is formed.
Explanation:
Friedel Craft alkylation is carried in presence of lewis acid. In this reaction the lewis acid is FeCl3 which abstract the chlorine from the haloalkane forming a carbocation.
Benzene act as nucleophile and carbocation acts as electrophile. The double bond interacts with carbocation forming a bond. The bonding with carbocation result in loss of resonance of benzene.
In order to regain the aromaticity the Hydrogen is abstracted and resonance is regained.
