Identify the set of reagents `//` reaction conditions `'X'` and `'Y'` in the following set of transformations.
`CH_(3)-CH_(2)CH_(2)Br overset(X)rarr P r od uct overset(Y)rarr`

A

`X` =dilute aqueous `NaOH,20^(@)C,Y=HB//` acetic acid `20^(@)C` .

B

`X=` concentrated alcoholic `NaOH,80^(@)C,Y =HBr//`acetic acid, `20^(@)C` .

C

`X=` dilute aqueous Na `OH,20^(@)C,Y =Br_(2)//CHCI_(3),0^(@)C` .

D

`X=` concentrated alcoholic `NaOH, 80^(@)C,Y=Br_(2)//CHCI_(3)`.

Text Solution

Verified by Experts

The correct Answer is:
B
Dehydrobromination by strong base (alcNaOH) followed by Markownikoff addition of `HBr` Dil bas carries out substitution Strong base at high temperature favours elimination .
