Question

Name the organic compound prepared by each of the following reactions:

${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{COONa}+\mathrm{NaOH}\to$

Answer 1

1. The chemical name of ${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{COONa}$ is Sodium propanoate.
2. The chemical name of $\mathrm{NaOH}$ is Sodium hydroxide.
3. Sodium propanoate (${\mathbf{C}}_{\mathbf{2}}{\mathbf{H}}_{\mathbf{5}}\mathbf{COONa}$) on heating with Sodium hydroxide ($\mathbf{NaOH}$) in presence of Calcium oxide ($\mathbf{CaO}$) forms Sodium carbonate (${\mathbf{Na}}_{\mathbf{2}}{\mathbf{CO}}_{\mathbf{3}}$) and Ethane (${\mathbf{C}}_{\mathbf{2}}{\mathbf{H}}_{\mathbf{6}}$).
4. The reaction is shown below.
   $$\begin{gathered} {\mathrm{C}}_2{\mathrm{H}}_5\mathrm{COONa}\left(\mathrm{aq}\right)+\mathrm{NaOH}\left(\mathrm{aq}\right)\underset{300°\mathrm{C}}{\overset{\mathrm{CaO}}{\to }}{\mathrm{Na}}_2{\mathrm{CO}}_3\left(\mathrm{aq}\right)+{\mathrm{C}}_2{\mathrm{H}}_6\left(\mathrm{g}\right) \\ \mathrm{Sodium}\mathrm{Sodium}\mathrm{Sodium}\mathrm{Ethane} \\ \mathrm{Propanoate}\mathrm{hydroxide}\mathrm{carbonate} \end{gathered}$$
5. Therefore, the organic compound prepared is Ethane.
