Question

how can you convert benzene into toluene

Answer 1

take reagent chcl3 dear

Answer 2

We can convert benzene into toluene by using Friedel craft alkylation reaction.

Explanation:

• Toluene is methyl ($CH_3$) group attached to benzene ring. we have to substitute only $CH_3$ group at any position of benzene to convert benzene to Toluene.

• Friedel craft alkylation involves the formation of carbocation and it is a type of Electrophilic Addition reaction. In this reaction we use chloromethane ($CH_3Cl$) and anhydrous aluminum chloride($AlCl_3$).

• There are three steps in this reaction-Generation of carbocation, attack of carbocation on benzene, regaining of aromaticity. All the steps and formation of Toluene are shown in attached picture.
