Vedclass · Answer

(A) Bromination of alkanes is a free radical substitution reaction. Bromine is highly selective and prefers to substitute the hydrogen on the more stable radical intermediate. In $n$-butane $(CH_3-CH_2-CH_2-CH_3)$,the secondary $(2^{\circ})$ carbon radical is more stable than the primary $(1^{\circ})$ carbon radical. Therefore,$2$-bromobutane $(CH_3-CH_2-CH(Br)-CH_3)$ is the chief product.

What is the chief product obtained when $n$-butane is treated with bromine in the presence of light at $130^{\circ}C$?
