Which product will form when optically active form of `C_4H_9Br ` is subjected to dehydrohalogenation? 

Text Solution

Verified by Experts

The optically active form of `C_4H_9Br` is `CH_3CH_2CHBrCH_3`. 2-Bromobutane on dehydrohalogenation gives 2-butene according to Saytzeff rule.
`CH_3CH_2CHBr CH_3 underset(KOH)overset("alcoholic")(rarr)CH_3CH = CHCH_3 + KBr + H_2O`.
