(a) Interpretation: The reason as to why the trityl radical is an unusually stable radical is to be stated. Concept introduction: Resonance is a phenomenon in which polarity is generated in a molecule by the interaction of the conjugated π - bonds or by interaction of the lone pair of electrons and π - bonds. In this phenomenon, the delocalization of the lone pair of electrons occurs. More the resonating structures of a compound, more stable is the compound.

Interpretation Introduction

(a)

Interpretation:

The reason as to why the trityl radical is an unusually stable radical is to be stated.

Concept introduction:

Resonance is a phenomenon in which polarity is generated in a molecule by the interaction of the conjugated π- bonds or by interaction of the lone pair of electrons and π- bonds. In this phenomenon, the delocalization of the lone pair of electrons occurs. More the resonating structures of a compound, more stable is the compound.

Interpretation Introduction

(b)

Interpretation:

The process of formation of a dimer, hexaphenylethane from the trityl radicals is to be stated.

Concept introduction:

Free radical addition reaction is a reaction in which two stable radicals or a radical and a non radical form a bond by sharing their radicals. The reaction takes place in three steps: chain initiation, chain propagation, and chain termination.

Interpretation Introduction

(c)

Interpretation:

The reason as to why the dimer of two trityl radical, ((4-(diphenylmethylene)cyclohexa-2, 5-dienyl)methanetriyl)tribenzene is formed instead of hexaphenylethane is to be stated.

Concept introduction:

Free radical addition reaction is a reaction in which two stable radicals or a radical and a non radical form a bond by sharing their radicals. The reaction takes place in three steps: chain initiation, chain propagation, and chain termination.
