(a)
Interpretation:
The passible mechanism should be drawn under given reaction conditions.
Concept Introduction:
Structure of the substrate plays major role in the reactivity of
Leaving group: it is a fragment that leaves substrate with a pair of electrons via heterolytic bond cleavage.
Nucleophile: donates pair of electrons to positively charged substrate resulting in the formation of
(b)
Interpretation:
The reactivity of the reaction under given conditions should be identified.
Concept Introduction:
Equation for the rate of E2 reaction is,
Rate Equation: It describes the rate of the reaction with respect to the concentration of the reactants participated in the reaction.
The relationship between the rate of the reaction and concentrations of the given nucleophile and
Thus,
Where, k is the rate constant.
