The molecular formula of an ester is ${\mathrm{HCOOCH}}_3$ . What will be the molecular formula of the alcohol and the acid from which it might be prepared?

What are the products formed when ethanoic acid reacts with sodium carbonate? Write the chemical equation for the reaction.

Name the following organic compound:

The compound that reacts with acetic acid to form ethyl ethanoate.

Read the description given below and say whether it fits for ethanol or ethanoic acid.

(i) It is used to preserve food and fruit juices.

(ii) On cooling, it is frozen to from ice flakes which looks like a glacier.

Complete the following table:

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

Name the above reaction.

Identify the substance underlined:

The organic compound which when solidified, forms an ice like mass.
