Write two physical properties of ethanol.

Answer the following:

Give a chemical equation for the reaction of Ethanol with excess hot conc. sulphuric acid.

Study the equation and answer the following:

${\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{OH} \underset{{\mathrm{H}}_2{\mathrm{SO}}_4}{\overset{\mathrm{hot} \mathrm{con}}{\to }} {\mathrm{CH}}_2={\mathrm{CH}}_2+\mathrm{CHO}$

What is the role of ${\mathrm{H}}_2{\mathrm{SO}}_4$ in the above reaction?

How ethanoic acid reacts with ${\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{OH}$ in presence of acid? Give chemical equation. :
