Answer 2

Explanation:

“Preparation of ethyl alcohol”:

Ethyl alcohol can be easily prepared by the sugar fermentation.

The chemical reaction is as follows:

$C_{6} H_{12} O_{6} \stackrel{\text { yeast }}{\longrightarrow} 2 C_{2} H_{5} O H+2 C O_{2}$

Properties of ethyl alcohol:

• Ethyl alcohol is a flammable and colorless liquid

• Ethanol has high octane number

• Molecular formula is $\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O}$

• Boiling point of ethanol is $173^{\circ} \mathrm{F}$

• Melting point of ethanol is $-173^{\circ} \mathrm{F}$

• Vapour pressure is 5.95 kPa

Uses of ethyl alcohol:

• Used as solvents for paints, varnishes and perfumes

• Preparation of Alcoholic drinks

• Used as a fuel for vehicles

• Making of ethanoic acid

• Preserving food.
