Question

Given, $100\%$ Ethyl alcohol is called ______.

Answer 1

Ethyl alcohol is sometimes referred to as “alcohol”. As the name suggests it has an alcoholic group in the structure. Its IUPAC name is ethanol, in which the suffix “-ol” represents the presence of an alcohol group. It consists of a straight chain of carbons. Its chemical formula is written as ${C_2}{H_5}OH$.

Complete answer:
We know that ethyl alcohol contains alcoholic functional groups. Its IUPAC name is ethanol, in which the suffix “-ol” represents the presence of an alcohol group. The name suggests that it contains two carbon atoms. Hence, the chemical formula of ethyl alcohol is ${C_2}{H_5}OH$ .
Ethyl alcohol has some chemical and physical properties like it is a flammable and volatile liquid. It is colourless liquid and has a characteristic odour.
Ethyl alcohol is soluble in water and it is mixed with water in different proportions. When a solution of ethanol and water contains $95\%$ ethanol and $5\%$ water, then it is known as rectified alcohol. Anhydrous ethanol is denatured for many purposes by adding five percent methanol (alcohol with one carbon atom) to it.
Therefore, $100\%$ Ethyl alcohol is called Absolute alcohol.

Note:
Ethyl alcohol has many applications like it is used as a solvent in many organic reactions. It is used in manufacturing perfumes, tinctures and paints. It is used as an additive in automotive gasoline. It is used as a disinfectant in laboratories and hospitals. It is also used in manufacturing of many medicines.
