Stability of Carbocations

    WP_20160129_12_51_13_Pro.jpg 1. The problem statement, all variables and given/known data


    2. Relevant equations


    3. The attempt at a solution
    Shouldn't the answer be 4?
    It certainly isn't 1 or 3 because they have maximum -I effect

    How did you conclude it was 4 after you narrowed it down to 2 and 4?

    OCH3 is an electron withdrawing group. So it will result in -R effect, making it less stable. Which leaves only option 4.

    OCH3 is -R? Are you sure
    I think you're confusing it with -I

    Oh, right. It has a +R effect, so more stable. Thank you!

    Have you officially been taught all these polar effects? Because that's in 12th.
    Are you reading ahead? If so I would advice you to solve from a book that provides detailed answers for these questions, it'll help you learn.

    At school we don't have any of these on syllabus, so I'm doing it on my own.

    Okay then as I said
    Choose a book with good solutions provided
    And after a while you'll get a hang of it
    Hey I think your school will have it next year ask your teacher
