Which type of compound is shown in the illustration?

a. a hydrocarbon
b. a halogen
c. a functional group
d. an ester

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.

Functional groups : Functional group are the groups which characterizes the particular group of compound. For example : is belongs to the alcohol family which contains as a functional group.

Halogen : The general formula of the halogen is, . It belongs to halide functional group in which the group (all the halogens) is directly attached to the alkyl group (R) of carbon.

Ester : The general formula of the ester is, . It belongs to ester functional group in which the the group is directly attached to the two alkyl group (R and R') of carbon.

The given compound is a saturated hydrocarbon that contains only hydrogen and the carbon atoms.

Therefore, the correct option is, (A) a hydrocarbon

diagram is missing, but i will try to explain your doubt.
