Understanding Simple Molecular Structures in Chemistry

[Barclay]

Homework Statement

What are simple molecular structures?

Homework Equations

The Attempt at a Solution

Simple molecular structures consist of molecules containing fixed numbers of atoms joined by strong covalent bonds.

I'm getting confused with all the different structures in chemistry. How simple is simple?Simple molecular structures are : water, CO₂ because they are not forming long chains as in diamond.

What about DNA? I think saw somewhere that DNA is a simple strucure (i may be wrong). Is it simple because the chians are a fixed size?

Dr Du I got that bit wrong ... I don't know what I was thinking. I just got confused with something about simple molecules have a fixed number of atoms.

But how simple is simple, for a molecule to be called a simple structure?

I don't think this is a rigidly defined expression. That's why I was asking about the context.
