1.	What is the chief product obtained when `n-`butane is treated with `Br_(2)` in the presence of light at `130^(@)C`?A. `CH_(3)CH_(2)CH_(2)CH_(2)Br`B. `Ch_(3) CH_(2)CHBrunderset(CH_3)underset(\|)CHBr`C. `Ch_(3) -CH_(2) HBrunderset(CH_2Br)underset(\|)CHBr`D. `Ch_(3) -CH_(2) HBrunderset(CH_3)underset(\|)CBr_(2)`
Answer» Correct Answer - B The reaction proceeds via free radical mechanism and rate of abstraction of `2^(@)` hydrogen is faster As `2^(@)` free radical is more stable tnan `1^(@)` , so `CH_(3) CH_(2) CH(Br)CH_(3) ` would be formed .
