(a)
To determine: A mechanism for the given reaction.
Interpretation: A mechanism for the given reaction is to be calculated.
Concept introduction: The
(b)
To determine: The structure of rate limiting transition state.
Interpretation: The structure of rate limiting transition state is to be drawn.
Concept introduction: The chemical reaction which proceeds through the formation of radicals is known as chain reaction. It involves three steps, initiation, propagation and termination. Generally, the initiation step occurs in the presence of light. The quantum yield of chain reactions is very high.

To determine: The intermediate that closely resembles to rate limiting transition state.
Interpretation: The intermediate that closely resembles to rate limiting transition state is to be predicted.
Concept introduction: According to Hammond’s postulate, the structure of transition state resembles to the structure of compound that has energy near to it.
