Reactions of Alkanes

Front

What is the role of UV light in the reaction of alkanes with bromine?

Back

UV light provides energy to break the covalent bond between Br atoms, initiating the reaction.

Front

What is the initiation step in the chlorination of alkanes?

Back

The initiation step involves the attack of chlorine radicals on alkanes.

Front

What is produced during the light-catalyzed fission of chlorine?

Back

Chlorine radicals are produced.

Front

What type of reaction occurs when alkanes react with bromine in the presence of UV light?

Back

Halogenation.

Front

What is a Free Radical Substitution Reaction?

Back

A reaction where free radicals replace atoms in a molecule, such as alkanes reacting with halogens.

Front

Define Halogenation.

Back

Halogenation is the reaction of alkanes with halogens (like bromine or chlorine) to form haloalkanes.

Front

What is a termination step in a free radical reaction?

Back

A termination step occurs when two free radicals combine to form a stable product, stopping the reaction.

Front

What is the difference between initiation and termination in free radical reactions?

Back

Initiation starts the reaction by generating free radicals, while termination ends the reaction by combining free radicals.

Front

What is the significance of bond dissociation energy in free radical reactions?

Back

Bond dissociation energy is the energy required to break a bond, influencing the rate of free radical reactions.

Front

What is a radical in chemistry?

Back

A radical is an atom or molecule that has unpaired electrons, making it highly reactive.
