Chapter 9, Problem 9.20P

(a)

Interpretation Introduction

Interpretation:

The rearranged structure of more stable carbocation has to be suggested.

Concept Introduction:

Stability order of carbocation:

A carbon containing three bonds with positive charge is known as carbocation.  This cat ion is stabilized by rearranging charge within the molecule.

The stability order of the carbocation is $\text{3°>2°>1°}$ .
