Question

Which one of the following represents saponification reaction.

• A. $C_2{H}_{5}OH\stackrel{alkaline{KMnO}_4}{\to }{CH}_{3}COOH$
• B. $2C_2{H}_{5}OH+2Na\to 2{CH}_3{CH}_{2}COONa+H_2$
• C. ${CH}_3{COOC}_2{H}_5+NaOH\to {CH}_{3}COONa+C_2{H}_{5}OH$
• D. ${CH}_{3}COONa+NaOH\stackrel{CaO}{\to }{CH}_4+{Na}_2{CO}_3$

Answer 1

The correct option is C

${\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5+\mathrm{NaOH}\to {\mathrm{CH}}_3\mathrm{COONa}+{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$

The long-chain carboxylic acids that contain Sodium $\left(\mathrm{Na}\right)$ and Potassium $\left(\mathrm{K}\right)$ salts are called soaps.

Soaps are biodegradable in nature. Soap does not produce lather in hard water.

The saponification reaction is the process of making soap by the reaction of oil or fat (Triglycerides) with alkaline Sodium hydroxide $\left(\mathrm{NaOH}\right)$ forms soap and alcohol.

The saponification reaction is represented as:

$$\begin{gathered} {\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5+\mathrm{NaOH}\to {\mathrm{CH}}_3\mathrm{COONa}+{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH} \\ (\mathrm{Ethyl}\mathrm{acetate})(\mathrm{Sodium}(\mathrm{Sodium}\left(\mathrm{Ethanol}\right) \\ \mathrm{hydroxide})\mathrm{acetate}) \end{gathered}$$.

Final answer:

Hence, option (C) is the correct option.
