Methanoic acid, $\text{HCO}_2\text{H}$, shows acidic behaviour in the same way as other carboxylic acids. It is also oxidised by the same oxidising agents that can oxidise aldehydes. Which pair of compounds would lead to the same 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 $\text{CH}_3\text{CH}_2\text{CHO}$
