What are halogenation of alkanes?Show answer
Alkanes are unreactive, but in the presence of ultraviolet light a halogen will substitute for a hydrogen atom. For example, methane reacts with chlorine:
What are hydrolysis of haloalkanes to alcohols?Show answer
A haloalkane can be converted to an alcohol by substitution of the halogen with a hydroxide ion. Warming a haloalkane with aqueous sodium hydroxide replaces the halogen:
