How are alkenes produced
WebAlkenes are produced from alkyl halides by dehydrohalogenation reactions. HX component of alkyl halide is removed from alkyl halide in the presence of a strong base to produce alkene. CH 3 CH 2 CL + KOH → KCL +CH 2 CH 2 +H 2 O What is the order of reactivity of alkyl halides?
