Q25 / 90 · JEE Main 2019 (10 Jan Shift 1) · Chemistry

Which hydrogen in compound $(E)$ is easily replaceable during bromination reaction in presence of light ?

A
$β$ - hydrogen
B
$δ$ - hydrogen
C
$α$ -hydrogen
Correct answer
D
$γ$ - hydrogen

Solution

Allylic radial is more stable due to resonance.

Rate of reaction

\propto

Stability of free radical

Hence, the correct answer is option: 'D'.
