Methanoic acid, $\text{HCO}_2\text{H}$, shows acidic behaviour like that of other carboxylic acids. It can also be oxidised by the same oxidising agents that oxidise aldehydes. Which pair contains two compounds that produce identical observations with Fehling’s reagent?
- A$\text{HCO}_2\text{H}$ and $\text{CH}_3\text{CO}_2\text{H}$
- B$\text{HCO}_2\text{H}$ and $\text{CH}_3\text{CO}_2\text{CH}_3$
- C$\text{HCO}_2\text{H}$ and $\text{CH}_3\text{CH}_2\text{COCH}_3$
- D$\text{HCO}_2\text{H}$ and $\text{CH}_3\text{CH}_2\text{CHO}$
