A compound $\mathrm{X}$ (having vinegar-like smell) when treated with ethanol in the presence of the acid, $\mathrm{Z}$, gives a compound $Y$ which has a fruity smell.
The reaction is
${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{O}\mathrm{H}+\mathrm{X}\stackrel{\mathrm{Z}}{\to }\mathrm{Y}+{\mathrm{H}}_2\mathrm{O}$
Name the above reaction.

Identify the substance underlined in the following case.
An organic compound containing $-\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}$ functional group.

Name an organic compound whose functional group is carboxyl.

Why is pure acetic acid known as glacial acetic acid?

Give a chemical equation for the reaction between ethyl alcohol and acetic acid.

The functional group present in acetic acid is

When acetaldehyde is oxidised with acidified potassium dichromate, it forms

Ethanoic acid reacts with ethanol in the presence of concentrated ${\mathrm{H}}_2{\mathrm{SO}}_4$, so as to form a compound and water. The chemical reaction which takes place is called:
