Chemistry - ALCOHOL & ETHER Question with Solution | TestHub

Given compound is tertiary alcohol (1-methylcyclohexanol).

In presence of H⁺/Δ, dehydration proceeds via E1 mechanism.

–OH leaves as water forming a tertiary carbocation.

This carbocation is already stable, so no rearrangement occurs.

Elimination of β-H takes place.

According to Saytzeff rule, more substituted alkene is formed.

Double bond forms within ring → 1-methylcyclohexene.

Hence, correct answer is (B).
