Question

which of the following types of molecular representations can be used to show differences between isomers? Explain why each can or cannot.

a) molecular formula
b) structural formula 
c) 3D drawing or model

thomaster · Answer

A cannot because the molecular formulas of isomers would be the same
B can because a structural formula is a graphic representation (in 2D) of the molecular formula.
C also can because a model is a structural formula in 3D.
