What can you learn from your models that you cannot by looking at structural formulas

Explanation:

With the help of models we get to know how atoms are bonded with each other. As a model tells how many numbers of atoms are attached to a central atom. Therefore, a models tells us the shape of a molecule.

For example, structure of molecule is as follows.

                                     O = C = O

Hence, structure of is linear in shape.
