Question

An example of carbon containing organic compound is :

• A. Water
• B. Carbon monoxide
• C. Sugar
• D. Calcium oxide

Answer 1

The correct option is C

Sugar

The explanation for the correct option :

(C) Sugar: The chemical formula for sugar is ${\mathrm{C}}_{12}{\mathrm{H}}_{22}{\mathrm{O}}_{11}$. An organic compound is the class of chemical compounds in which one or more carbon atoms are covalently bonded to another carbon atoms via single, double or triple bonds and other elements mostly hydrogen, nitrogen, and oxygen atoms. So sugar is an organic compound.

The explanation for the incorrect option :

(A) Water: The chemical formula of water is ${\mathrm{H}}_2\mathrm{O}$. It does not contain carbon. So it is not an organic compound.

(B) Carbon monoxide: The chemical formula of Carbon monoxide is $\mathrm{CO}$. It does not have any covalent bond with hydrogen. So, Carbon monoxide is not an organic compound.

(D) Calcium oxide: The chemical formula of Calcium oxide is $\mathrm{CaO}$. It is formed of ${\mathrm{Ca}}^{2+}$and ${\mathrm{O}}^{2-}$ ions and is not a covalent and organic compound. So, Calcium oxide is not an organic compound.

Thus, the correct option is (C) i.e. Sugar.
