What happens in the initiation step of the halogenation of an alkane?
1 point
UV light breaks the halogen molecule bond via homolytic fission, resulting in a halide anion and cation.
UV light breaks the halogen molecule bond via homolytic fission, resulting in two halogen free radicals.
UV light breaks the halogen molecule bond via heterolytic fission, resulting in a halide anion and cation.
UV light breaks the halogen molecule bond via heterolytic fission, resulting in two halogen free radicals.
