Question

Name the following: An organic acid forming $\mathrm{CO}$ and ${\mathrm{CO}}_2$ by dehydrating with conc.${\mathrm{H}}_2{\mathrm{SO}}_4$.

Answer 1

Organic acid:

The acids that are naturally present in plant bodies and animals are known as organic acids.

Determining the name of organic acid:

1. The name of organic acid is oxalic acid ${\left(\mathrm{COOH}\right)}_2$ that reacts with conc. ${\mathrm{H}}_2{\mathrm{SO}}_4$ (sulfuric acid) to give a mixture of $\mathrm{CO}$ (carbon monoxide), ${\mathrm{CO}}_2$(carbon dioxide) and water$\left({\mathrm{H}}_2\mathrm{O}\right)$.
2. The equation of the reaction is shown below

$$\begin{gathered} {\left(\mathrm{COOH}\right)}_2+\mathrm{conc}.{\mathrm{H}}_2{\mathrm{SO}}_4\to \mathrm{CO}+{\mathrm{CO}}_2+{\mathrm{H}}_2\mathrm{O} \\ \mathrm{oxalic}\mathrm{acid}\mathrm{Sulphuric}\mathrm{acid}\mathrm{Carbon}\mathrm{Carbon} \\ \mathrm{monoxide}\mathrm{dioxide} \end{gathered}$$

Therefore, oxalic acid is the organic acid forming $\mathrm{CO}$ and ${\mathrm{CO}}_2$ by dehydrating with conc.${\mathrm{H}}_2{\mathrm{SO}}_4$.
