Question

What can occur with chlorine and a source of direct UV?

1) Free radical halogenation
2) Substitution reaction
3) Addition reaction
4) Elimination reaction

Answer 1

Chlorine can undergo free radical halogenation when exposed to direct UV light. This reaction involves the substitution of a hydrogen atom in a compound with a chlorine atom, resulting in the formation of a haloalkane. An example of this reaction is the reaction between methane and chlorine to form methyl chloride.

Step-by-step explanation:

When chlorine reacts with a source of direct UV, a free radical halogenation reaction can occur. This means that a chlorine atom replaces a hydrogen atom in the compound, resulting in the formation of a haloalkane. For example, when methane (CH4) reacts with chlorine (Cl2) in the presence of UV light, methyl chloride (CH3Cl) is formed.
