Mark the correct increasing order of reactivity of the following compounds with HBr/HCl.

A

`(I)lt(II)lt(III)`

B

`(II)lt(I)lt(III)`

C

`(II)lt(III)lt(I)`

D

`(III)lt(II)lt(I).`

Text Solution

Verified by Experts

The correct Answer is:
C
It the correct decreasing order of acidic strength. All are benzyl alcohols with subsitutents present in two cases at the para position. A benzyl carbocation intermediate is formed on reacting with the acid. The reactivity of alcohols is linked with the relative stability of the carbocation formed.

`NO_(2)` group is more electron withdrawing than CI and both tend to destabilise benzyl carbocation. The increasing order of reactivity is : `(II) lt (III) lt (I)`
