Q13 / 90 · JEE Main 2022 (29 Jun Shift 2) · Chemistry

Which of the following carbocations is most stable:

  • A

    Figure

  • B

    Figure

  • C

    Figure

     

  • Correct answer
    D

    Figure

     

Solution

All these carbocations are stabilised by resonance. But the one which has maximum conjugation or maximum resonating structures will be most stable.

Figure

Is most stable carbocation since it has maximum conjugation and also it is stabilised due to mesomeric effect of methoxy group.

Hence, the correct answer is option: 'D'.
