Chapter 24, Problem 24.73P

Interpretation Introduction

(a)

Interpretation: The stepwise mechanism for the reaction of $\text{4-Methylpyridine}$ with benzaldehyde $\left({\text{C}}_{\text{6}}{\text{H}}_{\text{5}}\text{CHO}\right)$ in the presence of base to form A. is to be drawn.

Concept introduction: Nucleophilic addition reaction is a type of organic reaction in which the nucleophile is added to an electrophilic site. In case of carbonyl compounds, the carbonyl carbon acts as an electrophilic site.

Interpretation Introduction

(b)

Interpretation: The validation of the fact that $\text{2-methylpyridine}$ or $\text{3-methylpyridine}$ undergo similar type of condensation reaction is to be stated with an explanation.

Concept introduction: Nucleophilic addition reaction is a type of organic reaction in which the nucleophile is added to an electrophilic site. In case of carbonyl compounds, the carbonyl carbon acts as an electrophilic site.
