$\alpha$-hydrogen

Vedclass · Answer

(A) In the presence of light,bromination of alkenes occurs via a free radical mechanism.The hydrogen atoms attached to the carbon atom adjacent to the double bond (allylic position) are the most easily replaceable because the resulting allylic radical is stabilized by resonance.In the structure $CH_3 - CH_2 - CH = CH_2$,the carbon atom adjacent to the double bond is the $CH_2$ group.The hydrogen atoms on this $CH_2$ group are known as the $\alpha$-hydrogens relative to the double bond.Therefore,the $\alpha$-hydrogen is the most easily replaceable.

Which hydrogen in compound $(E)$ is easily replaceable during bromination reaction in the presence of light?
$CH_3 - CH_2 - CH = CH_2$
$(E)$
