Question

Which alkane is used for the preparation of toluene?

Answer 1

Methane could be used but not directly. First methane is reacted with chlorine to give chloromethane and that chloromethane is reacted with AlCl3 to form CH3+ and AlCl4

This is reacted with benzene C6H6

This yields toluene as CH3+ replaces a hydrogen from benzene
