Concept explainers
(a)
Interpretation:
The more reactive compound should be identified from the given pair compounds for an E2 reaction under strong base conditions.
Concept Introduction:
Elimination Reaction: It is just reverse reaction of addition where substituent from the given molecule is removed via
In an elimination reaction,
E2 reaction is a bimolecular elimination reaction in which only one step is involved and both the substrate and base are depending upon the
The reactivity of substrates are depends upon the transition state and the stability of formed alkene product.
The more substituted alkenes are more stable as compared to less substituted alkenes. The more alkyl group attachment to a double bond make it more stable due to the +I effect of alkyl groups. It means the alkyl groups will push electrons towards the double bonded carbon atoms, so the double bond becomes strengthened and highly stabilized.
Solvolysis: The reaction is defined as solvolysis reaction if solvent acts as nucleophile in the given reaction.
(b)
Interpretation:
The more reactive compound should be identified from the given pair compounds for an E2 reaction under strong base conditions.
Concept Introduction:
Elimination Reaction: It is just reverse reaction of addition where substituent from the given molecule is removed via
In an elimination reaction, alkenes are formed when alkyl halides are treated with bases via eliminating one β-proton and one α-halo group of the alkyl halide.
E2 reaction is a bimolecular elimination reaction in which only one step is involved and both the substrate and base are depending upon the rate of reaction.
