Arrange the following alcohols in the increasing order o reactivity with HBr. |
(I) benzyl alcohol |
(II) p-methyl benzyl alcohol |
(III) p-nitrobenzyl alcohol |
(IV) p-chlorobenzyl alcohol |
A) I<II<III<IV
B) III<IV<I<II
C) II<I<IV<III
D) IV<II<II<I
Correct Answer: B
Solution :
[b] Reactive intermediate carbocation is involved, hence greater the stability of carbocation, greater the reactivity of corresponding alcohols. Stability order = B > A > D > C Reactivity = II > I > IV > IIIYou need to login to perform this action.
