The order of reactivity of the following alcohols towards cone. HCl is

A) I>II>III>IV      

B) I>III>II>IV

C) IV>III>II>I      

D) IV>III>I>II

Correct Answer: C

Solution :

[c] The order of reactivity depends upon the stability of the carbocations formed. Stability of carbocations is in the order. Hence the order of relative reactivity of the alcohols will follow the order: IV>III>II>I
