Answer : The correct option is, (A) a hydrocarbon
Explanation :
Hydrocarbon : It is an organic compound that contains only hydrogen and the carbon atoms. They are of two types which are saturated hydrocarbon and unsaturated hydrocarbon.
- Saturated hydrocarbons : It is defined as the hydrocarbons in which a single bond is present between the carbon-carbon atoms. The general formula for these hydrocarbons is [tex]C_nH_{2n+2}[/tex]
- Unsaturated hydrocarbons : It is 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 [tex]C_nH_{2n}[/tex] and [tex]C_nH_{2n-2}[/tex]
Functional groups : Functional group are the groups which characterizes the particular group of compound. For example : [tex]CH_3OH[/tex] is belongs to the alcohol family which contains [tex]-OH[/tex] as a functional group.
Halogen : The general formula of the halogen is, [tex]R-X[/tex]. It belongs to halide functional group in which the [tex]-X[/tex] group (all the halogens) is directly attached to the alkyl group (R) of carbon.
Ester : The general formula of the ester is, [tex]R-COO-R^'[/tex]. It belongs to ester functional group in which the the [tex]-COO[/tex] group is directly attached to the two alkyl group (R and R') of carbon.
The given compound [tex]C_3H_8[/tex] is a saturated hydrocarbon that contains only hydrogen and the carbon atoms.
Therefore, the correct option is, (A) a hydrocarbon
