(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:

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.

In unpolluted air at 300 K, the hydroxyl radical OH reacts with CO with a bimolecular rate constant of 1.6 × 101' L mol-1 s-1 and with CH4 with a rate constant of 3.8 × 10° L mol¬1 s-1. Take the partial pressure of CO in air to be constant at 1.0 × 10-7 atm and that of CH4 to be 1.7 x 10-6 atm, and assume that these are the primary mecha- nisms by which OH is consumed in the atmosphere. Cal- culate the half-life of OH under these conditions.

This reaction does not take place. All that happens under experimental conditions for the formation of radicals is initiation to form iodine radicals, I·, followed by termination to reform I2. How do you account for these observations?

Some reactions proceed through a chain mechanism involving radicals, which are highly reactive species with one or more unpaired electrons. The radicals are produced in initiation steps, through either thermal or photodissociation. Reactions in which the radical centre is transferred are called propagation steps. The radicals are lost in termination steps. Consider the following chain mechanism:(1) AH → A + H·(2) A → B· + C(3) AH + B· → A + D(4) A + B· → P(a) Identify the initiation, propagation, and termination steps.(b) Use the steady-state approximation to deduce that the decompositionof AH is f irst-order in AH.
