(a)
Interpretation: The two main products of the indicated reaction should be drawn.
Concept introduction:Carbocations generated from
If the leaving group present eliminates along with a proton in absence of any strong nucleophile the double bond formation might occur. Such reactions are known as two-step unimolecuar elimination, abbreviated as
(b)
Interpretation: The mechanism I should be identified.
Concept introduction: Carbocations generated from alkyl halides have two fates; they can be either trapped by nucleophiles to give substitution product or may deprotonate to yield a small amount of alkene.
If the leaving group present eliminates along with a proton in absence of any strong nucleophile the double bond formation might occur. Such reactions are known as two-step unimolecuar elimination, abbreviated as
(c)
Interpretation: The mechanism II should be identified.
Concept introduction: Carbocations generated from alkyl halides have two fates; they can be either trapped by nucleophiles to give substitution product or may deprotonate to yield a small amount of alkene.

(d)
Interpretation: The approximate molar concentration of sodium methoxide that would cause the two mechanisms to proceed at same rate mechanism should be identified.
