Vedclass · Answer

(D) The bromination of alkanes follows a free radical mechanism.
Bromine is highly selective and preferentially replaces the hydrogen atom on the carbon that forms the most stable radical.
In $2-$methylbutane $(CH_3-CH(CH_3)-CH_2-CH_3)$,the $C2$ position is a tertiary $(3^\circ)$ carbon.
The $3^\circ$ radical is significantly more stable than $2^\circ$ or $1^\circ$ radicals.
Thus,the major product is $2-$bromo$-2-$methylbutane.

The major product obtained in the photo-catalyzed bromination of $2-$methylbutane is:
