Write the structures of all possible isomers of ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_2$.

What is the IUPAC name of formic acid?

• Take $150\mathrm{mL}$ water in a beaker and warm it to ${60}^{\circ }\mathrm{C}$.
• Take two test tubes and label them $\mathrm{A}$ and $\mathrm{B}$ respectively.
• Take $5\mathrm{mL}$ ethanol in test tube $\mathrm{A}$.
• Take $5\mathrm{mL}$ glacial acetic acid in test tube $\mathrm{B}$ and add $4$ to $5$ drops concentrated sulphuric acid to it.
• Now add the solution in the test tube $\mathrm{A}$ to the solution in test tube $\mathrm{B}$.
• Now place the test tube in the warm water so that the reaction mixture also becomes warm. Keep shaking the test tube from time to time.
• Pour the reaction mixture in a solution of sodium hydrogen carbonate in water. Doing this will cause the unreactive ethanoic acid to react with ${\mathrm{NaHCO}}_3$. Did you see any bubbles? 
• Observe the reaction mixture and note if there is any distinct smell (sweet and fruity). The smell could be due to which substance?
