Interpretation Introduction

Interpretation: The carbonyl compounds among the given compounds that do not undergo an aldol reaction on treatment with ${}^{-}\text{OH}$ present in ${\text{H}}_{\text{2}}\text{O}$ are to be stated.

Concept Introduction: Aldol reaction is the condensation reaction of the organic chemistry. In this reaction an enolate ion or an enol reacts with the carbonyl compound that leads to the formation of $\text{β}$-hydroxyaldehyde or $\text{β}$-hydroxyketone which on further dehydration gives the conjugated enone.
