Vedclass · Answer

(A) The reaction of $1	ext{-methylcyclohexanol}$ with $	ext{conc. } H_2SO_4$ at high temperature involves acid-catalyzed dehydration. This proceeds via an $E1$ mechanism,where the hydroxyl group is protonated and leaves as water to form a tertiary carbocation. Subsequent loss of a proton from the adjacent carbon leads to the formation of the more stable,more substituted alkene,which is $1	ext{-methylcyclohexene}$ $(A)$.The reaction of $1	ext{-methylcyclohexanol}$ with $CH_3COCl$ in the presence of pyridine is an acetylation reaction. The alcohol acts as a nucleophile,attacking the acetyl chloride to form an ester,$1	ext{-methylcyclohexyl acetate}$ $(B)$.

Identify the major products $A$ and $B$ respectively in the following set of reactions.
