Question

Which of the following compounds is an unsaturated hydrocarbon?

Answer 1

Answer:

Explanation:

Saturated hydrocarbons are defined as the hydrocarbons in which a single bond is present between carbon and carbon atoms.These are called as alkanes. The general formula for these hydrocarbons is $C_nH_{2n+2}$

Unsaturated hydrocarbons are defined as the hydrocarbons which have double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is $C_nH_{2n}$ and $C_nH_{2n-2}$.

1. Propyne is $C_3H_4$ and is an unsaturated hydrocarbon.

2. Methane is $CH_4$ and is a saturated hydrocarbon

3. Nonane is $C_9H_{20}$ is a saturated hydrocarbon.

4. Methyl is $CH_3$ and is a saturated alkyl group.
