An organic compound $\text{C}_2\text{H}_4\text{O}$ gives red precipitate when heated with Fehling solution. It also undergoes aldol condensation in the presence of dilute $\text{NaOH}$.
Identify the organic compound and write its IUPAC name.
Answer
Answer
The compound is $\text{CH}_3\text{CHO}$: it reduces Fehling's solution (red precipitate of $\text{Cu}_2\text{O}$), so it is an aldehyde, and it has $\alpha$-hydrogens, so it undergoes aldol condensation. IUPAC name: ethanal (acetaldehyde).
