JEE Main · 2022 · 28 Jun 2022 · Shift 2 · Alcohols Phenols and Ethers

The major product (P) of the given reaction is (where, Me is

- CH_{3}

)

(A)(see structure)
(B)(see structure)
(C)(see structure)
✓ Correct
(D)(see structure)

Answer: (C)

Solution

The reaction involves dehydration of an alcohol under acidic conditions (conc.

H_{2} SO_{4}

, heat). The major product follows Zaitsev's rule, forming the more substituted alkene. The carbocation intermediate rearranges to give the most stable product, which is the tetrasubstituted cyclohexene shown in option (C) with two methyl groups on the double bond carbons.
