Dear Rajata,

Carbocation is formed in the reaction where Hexane on reaction with anhydrous undergoes rearrangement reaction forming secondary carbocation which ultimately forms 2-methyl pentene.

Hello aspirant

Carbonation intermediate is formed in reaction

Hexane + ( anhydrous AlCl / HCl ) → 2- methyl pentane

Hexane on reaction with anhydrous AlCl3 undergoes re arrangement reaction firming a secondary carbonation which ultimately forms 2- methyl pentane.
