What is the correct order of decreasing stability of the following cations?

(i) II > I > III

(ii) II > III > I

(iii) III > I > II

(iv) I > II > III

Answers (1)

(i) II > I > III

Explanation: In the case of (I) +vely charged C is attached to two alkyl groups and so the +I effect stabilizes the carbocation. In the case of (II), the +R effect of OCH_3 the group stabilizes the carbocation. In the case of (III), the - I effect of -OCH_3 gp, destabilizes the carbocation; hence, the order of stability will be such: II > I >III.
