The general reaction scheme is as follows: R-X + Nu - R-Nu + X - Where R is an alkyl chain, X is the halide ion and Nu the nucleophile. Reaction with hydroxide ions WebWhen haloalkane or alkyl halide with a β - hydrogen atom is heated with alcoholic solution of potassium hydroxide (alc.KOH), the OC 2H 5− ion acts as a base and eliminate an hydrogen from β - carbon atom then this elimination is known as β - elimination. There is also a simultaneous elimination of halogen atoms from α - carbon. huarache utility gym red
