Concept explainers
(a)
Interpretation:
An explanation as to why the hydrogens of the methyl group shown in red, as well as the imide proton, are readily exchanged for deuterium by dilute
Concept introduction:
The nucleophilic substitution reactions depend upon the nucleophilicity and concentration of the nucleophile. There are two types of nucleophilic substitution reaction.
The carbon which acquires a negative charge act as nucleophile and it is known as a carbanion. The resonance occurs due to the delocalization of
(b)
Interpretation:
An explanation as to why the hydrogens of the methyl group shown in red are most acidic, even though the other methyl group is directly attached to the positively charged nitrogen is to be stated.
Concept introduction:
The nucleophilic substitution reactions depend upon the nucleophilicity and concentration of the nucleophile. There are two types of nuclephilic substitution reaction.
The carbon which acquires a negative charge acts as nucleophile and it is known as carbanion. The resonance occurs due to the delocalization of

Interpretation:
An explanation as to why the given reaction takes place in aqueous base is to be stated.
Concept introduction:
The hydrolysis is a
The nucleophilic substitution reactions are the reactions in which one nucleophile is substituted by another nucleophile.

Interpretation:
An explanation as to why the compound,
Concept introduction:
Hydrolysis is a chemical reaction in which the water molecule is breaks the bonds between two or more molecules in a compound. The term is generally used for the elimination and substitution reaction in which water molecule act as a nucleophile.

- 1. For each of the following statements, indicate whether they are true of false. ⚫ the terms primary, secondary and tertiary have different meanings when applied to amines than they do when applied to alcohols. • a tertiary amine is one that is bonded to a tertiary carbon atom (one with three C atoms bonded to it). • simple five-membered heteroaromatic compounds (e.g. pyrrole) are typically more electron rich than benzene. ⚫ simple six-membered heteroaromatic compounds (e.g. pyridine) are typically more electron rich than benzene. • pyrrole is very weakly basic because protonation anywhere on the ring disrupts the aromaticity. • thiophene is more reactive than benzene toward electrophilic aromatic substitution. • pyridine is more reactive than nitrobenzene toward electrophilic aromatic substitution. • the lone pair on the nitrogen atom of pyridine is part of the pi system.arrow_forwardThe following reactions are NOT ordered in the way in which they occur.
