Suggest the name of a Lewis acid other than anhydrous aluminium chloride which can be used during ethylation of benzene.

Text Solution

Verified by Experts

Ethylation means introduction of an ethyl group in the benzene ring. This is usually carried out by Friedel-Crafts reaction of benzene with ethyl halide (chloride or bromide ) , ethene or ethanol. The Lewis acid catalysts other than anhydrous `AlCl_3` used in this reaction are : anhydrous `FeCl_3,SnCl_4, BF_3` etc.
