To determine: If the free-radical chlorination is a reasonable way to make monochlorinated derivatives of given compounds or not and if the reaction would give one major product.
Interpretation: If the free-radical chlorination is a reasonable way to make monochlorinated derivatives of given compounds or not is to be predicted and if the reaction would give one major product is to be stated.
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.
