Chapter 9.3, Problem 9.4P

(a)

Interpretation Introduction

Interpretation:

The additional resonance contributing structure of given carbocation has to be drawn and greater contributing resonance hybrid has to be stated.

Concept Introduction:

Stability of carbo cation:

The highly substituted carbocation is more stable so the stability of carbocation is give as,

3°>2°>1°

Resonance contributor:

Two forms of a molecule that contains same chemical connectivity with different electron distributions are known as resonance structures.  They are used to explain the stability of molecule.
