Question

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

I. \[\ce{CH3 - \overset{⊕}{C}H - CH3}\]
II. \[\ce{CH3 - \overset{⊕}{C}H - OCH3}\]
III. \[\ce{CH3 - \overset{⊕}{C}H - CH2 - OCH3}\]

Options

  • II > I > III

  • II > III > I

  • III > I > II

  • I > II > III

MCQ

Solution

II > I > III

Explanation:

Thus, the stability of carbocations decreases in the order: II > I > III.
