Question 14 • Biology

What is a disadvantage of using a structural model to show a chemical compound?

Answer
A
Structural models cannot distinguish between different isomers of a compound.
B
Structural models cannot distinguish between single, double, and triple bonds.
C
Structural models do not identify the number and type of each atom.
D
Structural models provide minimal three-dimensional information.

Explanation

Structural models show how atoms are connected and can represent single, double, and triple bonds, so they can distinguish isomers and show the kinds and numbers of atoms. However, a flat structural formula gives limited information about the molecule’s three-dimensional shape and spatial arrangement. Therefore, the disadvantage is that structural models provide minimal three-dimensional information.
