The alcohol has a higher priority in nomenclature than alkenes, alkynes, alkyl groups and halogen and is given a number lower than any of those groups.

5-Reactions of Hydrocarbons - Laney College
laney.eduJan 05, 2012 · Alkenes and alkynes are much more reactive than alkanes. They will react readily with Br 2 or Cl 2, and ultraviolet light is not needed for the reaction. This reaction is an addition reaction – the halogen atoms will add at the site of the double bond only. Therefore, this reaction is selective– only one product will result.
