Chapter 6, Problem 6.81P

Interpretation Introduction

Interpretation:

Among the two molecules ${\text{CH}}_3\text{CN}$ and ${\text{CH}}_3\text{NC}$, the stronger acid is to be determined, with explanation.

Concept introduction:

The acidity of a compound is governed largely by the functional group on which the acidic proton is found. The acid with the lower pKa value is the stronger acid. While comparing two uncharged acids, the stronger acid is the one whose negatively charged conjugate base is more stable. Delocalization of the charge via resonance lowers the concentration of the charge and increases the stability of the charged species.
