(a) Interpretation: The structure for carbocation A is to be predicted. The resonance structures of carbocation A are to be drawn. Concept introduction: Most of the organic structures cannot be represented using a single Lewis structure. Therefore, there exists more than one Lewis structure for representing a molecule or ion. These structures are known as resonance structures. These resonance structures combine together to give resonance hybrid that is lower in energy and is the most stable structure.

Interpretation Introduction

(b)

Interpretation:

The reason as to why the structure of A is in consistence with the NMR data is to be stated.

Concept introduction:

Proton NMR spectroscopy identifies the number of hydrogen atoms present in a molecule and the nature of the functional group. The value of chemical peaks depends upon the chemical environment around the hydrogen atom.

Interpretation Introduction

(c)

Interpretation:

The reason as to why the NMR spectrum of A becomes a single line when the temperature is raised to 113 °C is to be stated.
