There are several different models that represent compounds. One type of model is shown.

3 C's connected in a line by 2 black lines. The first and third C's each have 3 H's connected to them by a single black line each. The middle C has 2 H's connected to it by a single black line each.
What type of model is shown?

a structural formula
a chemical formula
a space-filling model
a ball-and-stick model

The correct option is A) structural formula

Explanation:

In the field of chemistry, a structural formula can be described as the formula which shows the arrangements of atoms in the compound or molecule.

The model describes the structural arrangement of the carbon and hydrogen atoms present in a molecule. Hence, it is an example of a structural formula.

Other options, like option B, are not correct because a chemical formula just represents the symbol of the elements present in a compound along with the number of atoms of the particular element.
