Major products A and B formed in the following reaction sequence, are:

  1. A

    1

  2. B

    2

  3. C

    3

  4. D

    4

Solution

PBr converts the secondary alcohol cleanly to the corresponding alkyl bromide (A = 4-methylcyclohexyl bromide).

Alcoholic KOH on a 2 alkyl bromide is a classic E2 elimination, giving the alkene B = 4-methylcyclohex-1-ene as the major product.
