Question

Which hydrogen in compound $(E)$ is easily replaceable during bromination reaction in presence of light :
$\underset{\delta }{C{H}_3}-\underset{\gamma }{C{H}_2}-\underset{\beta }{\mathrm{CH}}=\underset{\alpha }{C{H}_2}$

• A. $\beta$- hydrogen
• B. $\gamma$ - hydrogen
• C. $\delta$ - hydrogen
• D. $\alpha$ - hydrogen

Answer 1

Answer: (B)

$\gamma$ - Hydrogen is easily replacable during bromination reaction in presence of light, because Allylic substitution is being preferred.
