Question

Match the compounds, Ethanol, Methane, Ethanoic acid, Ethyne, and Ethene with the description given below:

It reacts with Sodium bicarbonate and liberates a colorless gas which turns lime water milky.

Answer 1

A functional group is defined as a group of atoms that exist in a molecule and describes the characteristics reactions of organic compounds is called a functional group.

The reaction of Sodium bicarbonate $\left({\mathrm{NaHCO}}_3\right)$ with Ethanoic acid $\left({\mathrm{CH}}_3\mathrm{COOH}\right)$ liberates a colorless gas which turns lime water milky.

The colorless gas produced in the reaction is Carbon dioxide $\left({\mathrm{CO}}_2\right)$, which turns lime water milky.

The chemical reaction of Ethanoic acid and Sodium bicarbonate is written as:

$$\begin{gathered} {\mathrm{CH}}_3\mathrm{COOH}+{\mathrm{NaHCO}}_3\to {\mathrm{CH}}_3\mathrm{COONa}+{\mathrm{CO}}_2+{\mathrm{H}}_2\mathrm{O} \\ (\mathrm{Ethanoic}(\mathrm{Sodium}(\mathrm{Sodium}(\mathrm{Carbon}\left(\mathrm{Water}\right) \\ \mathrm{acid})\mathrm{bicarbonate})\mathrm{acetate})\mathrm{dioxide}) \end{gathered}$$
