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 alcoholic `NaOH, 80^(@)C` , Y = `Br_(2)//CHCl_(3)0^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
B
`CH_(3)-CH_(2)-CH_(2)Br overset(Conc.NaOH(alc),80^(@)C)underset(-NaBr, -H_(2)O)rarr`
`CH_(3)-CH=CH_(2)overset("HBr/acetic acid" 20^(@)C)rarr CH_(3)-underset(Br)underset(|)(C )H-CH_(3)`
Therefore, X is concentrated alcoholic `NaOH, 80^(@)C` and Y is HBr/acetic acid `20^(@)C`.
