I. `CH_(2)=CHCH_(2)Cl`
II. `CH_(3)CH_(2)CH_(2)Br`
III. `(CH_(3))_(3)C CH_(2)Br`
IV. `CH_(3)CH_(2)CH_(2)Cl`

A

`IIltIIIltIVltI`

B

`IIIltIIltIVltI`

C

`IVltIIIltIltII`

D

`IIIltIVltIIltI`

Text Solution

Verified by Experts

The correct Answer is:
D
Order of reactivity of different alkyl halides towards Williamson.s synthesis is Allyl `gt1^(@)gt2^(@)gt3^(@)`.
For same alkyl group order of reactivity is `R-IgtR-BrgtR-Cl`.
Thus order of reactivity of given alkyl halides towards Williamson.s synthesis can be given as
`CH_(2)=CHCH_(2)Cl("Allyl")gtCH_(3)CH_(2)CH_(2)Br(1^(@)"bromide")gtCH_(3)CH_(2)CH_(2)Cl(1^(@)"chloride")gt(CH_(3))_(3)C CH_(2)Br("Sterically hindered")`
