Question

What is a disadvantage of using a space-filling model to show a chemical compound? Space-filling models provide a two-dimensional view of the molecule. Space-filling models do not identify the number and type of bonds. Space-filling models do not show all atoms in the molecule. Space-filling models show information about composition but not structure.

Answer 1

The appropriate answer is 'space filling models do not identify the number and type of bonds'. A space filling model is one type of three dimensional (3D) molecular model used to represent molecules of different chemical compounds. The structure of this type of arrangement shows that, for example, two elements are bonded but it does not show if it is a single, double or triple bond. 
 

Answer 2

The disadvantage of using a space-filling model to show a chemical compound is space-filling models do not identify the number and type of bonds.

The correct option is (b)

What are space filing models?

A space-filling model, also known as a calotte model in chemistry, is a three-dimensional (3D) molecular model.

It's also known as the CPK model after the scientists, Robert Corey, Linus Pauling, and Walter Koltun.

This model is useful to see the shape and relative dimension of the molecule.

Thus, option (B) Space-filling models do not identify the number and type of bonds, is correct.
