Question

Which of the following is an organic molecule? a. so2 b. c3h8 c. h2o d. lif

Answer 1

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.

Answer 2

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.
