Carbocation as an intermediate is likely to be formed in the reaction :

Options

AAcetone (+ HCN - OH ) acetonecyanohydrin
BHexane ( anhy.AlCl / HCl )
CPropene (+ Cl ₂ hv ) 2-chloropropane
DEthylbromide (+ ) aq. ( KOH ) ethyl alcohol

Correct answer

B. Hexane ( anhy.AlCl / HCl )

Step-by-step solution

The second reaction involves methyl group migration to the most stable carbocation. In the question, temperature ( 300^ C ) should be mentioned. Acetone cyanohydrin Ethanol
