Organic Chemistry Basics 2 Question 23

23. In the following carbocation; $\mathrm{H} / \mathrm{CH}_{3}$ that is most likely to migrate to the positively charged carbon is

(2009)

(a) $\mathrm{CH}_{3}$ at $\mathrm{C}-4$

(b) $\mathrm{H}$ at $\mathrm{C}-4$

(c) $\mathrm{CH}_{3}$ at $\mathrm{C}-2$

(d) $\mathrm{H}$ at $\mathrm{C}-2$

Show Answer

Solution:

  1. $\mathrm{H}$ at $\mathrm{C}_{2}$ will migrate giving resonance stabilised carbocation.
