Question

Choose the correct word/phrase from within the brackets to complete the sentence.
Ethanoic acid reacts with ethanol in the presence of concentrated $H_2{\mathrm{SO}}_4$ so as to form a compound and water.
The chemical reaction which takes place is called (dehydration/hydrogenation/esterification).

Answer 1

The correct option is Esterification.

When Acetic Acid/Ethanoic Acid $\left({\mathrm{CH}}_3\mathrm{COOH}\right)$ reacts with Ethanol in the presence of concentrated $H_2{\mathrm{SO}}_4$ Sulphuric acid they give off a sweet fruity smelling a compound called Ethyl Ethanoate ${\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5$

$$\begin{gathered} {\mathrm{CH}}_3\mathrm{COOH}+{\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{OH}\to {\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5+{\mathrm{H}}_2\mathrm{O} \\ AceticAcid\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}EthylAlcohol\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}EthylEthanoate\mathit{}\mathit{}\mathit{}\mathit{}Water \end{gathered}$$

This process is called esterification.

Ethanoic acid reacts with ethanol in the presence of concentrated $H_2{\mathrm{SO}}_4$ to form a compound and water. The chemical reaction which takes place is called esterification.
