(a)
Interpretation:
Major elimination product should be given, when given
Concept Introduction:
An E1 reaction is a two-step reaction in which the alkyl halide dissociates forming a carbocation intermediate. Then a base removes a proton from adjacent carbon to a positively charged carbon.
Major product is more stable
An E2 reaction is a concerted, one-step reaction in which the proton is the more stable alkene, unless the reactants are sterically hindered or the leaving group is poor.
(b)
Interpretation:
Major elimination product should be given, when given alkyl halide reacts with strong base and weak base.
Concept Introduction:
An E1 reaction is a two-step reaction in which the alkyl halide dissociates forming a carbocation intermediate. Then a base removes a proton from adjacent carbon to a positively charged carbon.
Major product is more stable alkene.
An E2 reaction is a concerted, one-step reaction in which the proton is the more stable alkene, unless the reactants are sterically hindered or the leaving group is poor.
