Question

Arrange the following in increasing order of stability?

• A. $2<1<3$
• B. $1<2<3$
• C. $3<1<2$
• D. $3<2<1$

Answer 1

The correct option is A $2<1<3$

Carbocation at cyclic propyl is more stable thus $\left(3\right)$ has carbocation attached to this type of $3$ groups and $\left(1\right)$ has 2 group.

Hence option A will be correct.
