Answer 1

Answer #1

In ques 9

Option a is correct as because both 1st and 2nd will go 1,2 methyl shift to form tertiary carbocation which is stable due to hyperconjugation.

Where as compound 3 undergoes a 1, 3 methyl shift which is much slower as compared to 1,2 methyl shift. Hence remaing all options are incorrect.
