The major product of reaction between n-butane and bromine at `130^(@)C` is

Options

A. `CH_3CH_2CH_2CH_2Br`
B. `CH_3CH_2undersetoverset(|)(CH_3)(CH)Br`
C. `CH_3-undersetoverset(|)(CH_2Br)(C)H_2CH_2Br`
D. `CH_3CH_2-undersetoverset(|)(CH_3)(C)HBr`

Answer

B

Explanation

`CH_3-CH_2-CH_2-CH_3 underset(Delta)overset(Br_2)(to)CH_3-CH_2-CH_2-CH_3+CH_3-CH_2-underset("major")underset(CH_3)underset(|)(C)H-Br`
As `2^@` free radical is more stable than `1^@` free radical
