When an alkyl halide is heated with alcoholic potassium hydroxide (alcoholic potash), hydrogen from beta carbon and halogen from alpha carbon would be eliminated.  Hence it is called Dehydrohalogenation reaction (De means detach, detach hydrogen from beta halogen from alpha).  As hydrogen of beta carbon is eliminated it is called beta elimination reaction.  This reaction follows Sytzef rule if the formed alkene is substituted one.  More substituted alkenes are produced as major product than least substituted alkene (C=C connected to more alkyl group would be formed as major product.
