What happens when ethyl alcohol and acetic acid react with each other in the presence of conc. $H_{2}SO_{4}$?

Which of the following is the use of acetic acid?

On dropping a small piece of sodium in a test tube containing carbon compound $X$ with molecular formula $C_{2}H_{6}O$,a brisk effervescence is observed and a gas $Y$ is produced. On bringing a burning splinter at the mouth of the test tube,the gas evolved burns with a pop sound. Identify $X$ and $Y$. Also,write the chemical equation for the reaction. Write the name and structure of the product formed when you heat $X$ with excess concentrated sulphuric acid.

Ethanol reacts with sodium and forms two products. These are:

Draw the structures for the following compounds:
$(i)$ Ethanoic acid
$(ii)$ Bromopentane
Are structural isomers possible for bromopentane?

$A$ gas is evolved when ethanol reacts with sodium. Name the gas evolved and also write the balanced chemical equation of the reaction involved.
