Question

In the following reaction order , B is
`CH_(3)CH_(2)COOH overset (P//Br_(2)) to A overset (alc KOH) underset (H^(+)) to B`
A. `CH_(2)=CH-COOH`
B. `CH_(2)-underset(Br)underset(|)(CH)-COOH`
C. `CH_(3)CH_(2)COBr`
D. `CH_(3)CH_(2)CH_(2)OH`

Answer 1

Correct Answer - A
`overset(alc.KOH)underset(H^(+))toCH_(2)=CH-COOH+HBr`
`P + Br_(2)` is a brominating agent that brominates the `alpha`-position. The product then undergoes dehydrohalogenation in the presence of alcoholic potassium hydroxide.
