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=HBr/acetic acid `20^@C`

B

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

C

X=dilute aqueous NaOH, `20^@C` ,
Y=`Br_2//CHCl_3, 0^@C`

D

X=concentrated alocoholic NaOH , `80^@C` ,
`Y=Br_2//CHCl_3, 0^@C`

Text Solution

Verified by Experts

The correct Answer is:
B
`CH_3-CH-CH_2Br overset("conc. Alcoholic")underset(NaOH(-HBr))(to) CH_3-CH=CH_2 overset(HBr)underset("Markownikoff addition")(to) CH_3 - undersetoverset(|)(Br)(C )H - CH_3`
