Alcohol (CH_3)_2CHCH_2OH cannot be obtained by

JEE Main Chemistry question

Alcohol cannot be obtained by

(A)
(B) (hydroboration–oxidation of isobutylene)
(C) (air oxidation)
(D)(CH_3)_2CHCHO + CH_3MgXCorrect

Answer: (D)

Solution

The target, isobutanol, , has its on a carbon bonded directly to an isopropyl group. In (a), formaldehyde plus isopropylmagnesium halide adds one carbon to give exactly this skeleton. In (b), anti-Markovnikov hydroboration–oxidation of isobutylene places on the less substituted
