Verified Answer :

Organic molecules have carbon atoms. Lithium Fluoride (LiF), water (H2O), and sulfer dioxide (SO2) have no carbon atoms

C3H8 (propane), because it has 3 carbon atoms. 


Answer: Option (b) is the correct answer.

Explanation:

A molecule that contains carbon and hydrogen atoms will be known as an organic compound.

For example, \(C_{3}H_{8}\) is an alkane molecule and it is an organic compound.

On the other hand, molecules that do not contain a carbon and hydrogen bond are known as inorganic compounds.

For example, \(H_{2}O\), \(SO_{2}\), and LiF are all inorganic compounds.

Therefore, we can conclude that out of the given options \(C_{3}H_{8}\) is an organic molecule.
