Absolute alcohol is:
1. $100\%$ Pure ethanol.
2. $95\%$ Alcohol and $5\% {H_2}O$.
3. Ethanol + water + phenol
4. $95\%$ Ethanol+$5\%$methanol

Answer 1

Absolute alcohol is a common name for alcohol, which purely contains alcohol and no other compound.
We will learn about the difference in absolute alcohol and rectified spirit since both have ethanol in common and it’s the concentration that creates the difference.

Complete answer:
There are many different categories of alcohol. The different categories are based on their uses. Some are used in laboratories, some are used in beverages and some are used in synthesizing other products. There is a different percentage of alcohol used in different categories. Also, there are different terms which are popularly studied in the chemistry of alcohol.
Rectified spirit: It is a pure concentration of alcohol which is produced by fractional distillation. It is used in medicines, households and mixed drinks.
Wood spirit: The wood spirit is a common name of methanol. It is not suitable for drinking as it harms the eyesight and your nervous system.
Denatured alcohol: Denatured alcohol is used in labs. To stop the consumption or misuse of alcohol in labs, the alcohol is mixed with methanol. To identify denatured alcohol, blue vitriol that is crystalline copper sulphate is mixed with alcohol to give it a blue colour appearance.
Absolute alcohol: Absolute alcohol means $99\%$ of pure ethanol. Ethanol is used in drinking beverages. Such as wine, whiskey, beer, etc.
And therefore the answer to the above question is $99\%$ ethanol.

Thus the correct answer to the given question is option A.

Note: Poor quality alcohol means methanol is mixed with ethanol in the beverage. Consumption of this alcohol which contains methanol is hazardous to your health. It can damage your nervous system and your eyesight. Several alcohol drinks which are not purified with that much of care leads to loss of many lives.
