Dehydrohalogenation

The elimination reaction is exactly what it sounds like. Use a base to take away (de-) one hydrogen and one halogen. Voila! We’ve got a double bond. 

Even more simply put, this is simply the name given to an E2 mechanism with a base an alkyl halide.

Example: Supply the mechanism and major/minor products for the following dehydrohalogenation reaction.
