2.

Which of the following is an essential condition for the free radical substitution reaction?
- Iron catalyst
- Nickel catalyst
- UV light
- Heating
Correct Answer

A. UV light

Explanation

UV light is an essential condition for the free radical substitution reaction because it provides the energy required to break the bond between the reactant molecules and create highly reactive free radicals. These free radicals then go on to react with other molecules, resulting in the substitution reaction. Without UV light, the reaction would not proceed as the necessary activation energy would not be met. The iron and nickel catalysts, as well as heating, are not necessary for this specific type of reaction.

9.

The following molecule is a product of the reaction.
- True
- False
Correct Answer

A. False

Explanation

FRS does not arbitrarily lengthen the carbon chain of the original hydrocarbon (ie. hexane). It may lengthen in multiples of the number of carbons in the hydrocarbon.

10.

The following molecule is a product of the reaction.
- True
- False
Correct Answer

A. True

Explanation

The given answer is true because the statement mentions that the molecule is a product of the reaction. Since the molecule is mentioned specifically as a product, it implies that it is indeed a result of the reaction.
