Question

$C_n{H}_{2n}{O}_n$ is the formula of

• A. Fatty acid
• B. Fat
• C. Glycerol
• D. Carbohydrate

Answer 1

Answer: (D)

Carbohydrate

Fatty acids act as a fuel for the body. It was discovered by Evans and Burr. It has a long chain of carbon atoms bonded to hydrogen atoms with the carboxyl group at the terminal end.

Fat is stored reserve for the body which provides energy. These are triesters of glycerol.

Glycerol has the chemical formula of C${}_3$H${}_8$O${}_3$. Fats are triesters of glycerol. It is obtained from fatty acids and glycerol. It consists of One glycerol molecule and three fatty acid molecules. The carboxyl end of the fatty acid combines with the three -OH groups of the glycerol to form ester

The monosaccharide is the simplest form of carbohydrate which is composed of carbon, hydrogen and oxygen. The basic formula of the monosaccharide is C${}_n$H${}_{2n}$O${}_n$. These are considered as the simplest form of sugar.

So, the correct answer is option D.
