What is meant by dehydrohalogenation?

Solution

Dehydrohalogenation is the elimination reaction shown by a haloalkane which involves the removal of the halogen atom together with a hydrogen atom bonded to a C atom adjacent to C atom bearing the halogen. As a result of dehydro– halogenation an alkene is formed. For example:

In the above reaction the Br atom bonded to carbon 1 and H atom bonded to carbon 2 of 1 -bromo propane are eliminate and propene is formed.
