Discussion Overview

The discussion revolves around the concept of simple molecular structures in chemistry, exploring definitions, examples, and the criteria that classify a molecule as having a simple structure. The scope includes conceptual clarification and homework-related inquiries.

Discussion Character

  • Conceptual clarification
  • Homework-related

Main Points Raised

  • Some participants define simple molecular structures as molecules with fixed numbers of atoms joined by strong covalent bonds, citing examples like water and CO2.
  • There is confusion regarding whether DNA qualifies as a simple molecular structure, with one participant questioning if its fixed chain size contributes to its simplicity.
  • Another participant expresses uncertainty about the definition of "simple" in this context, suggesting that it may not be rigidly defined.
  • Some participants seek clarification on the sources of information regarding these definitions.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the definition of simple molecular structures, with multiple competing views and uncertainties expressed regarding specific examples like DNA.

Contextual Notes

The discussion highlights limitations in the definitions provided, as well as the dependence on context for understanding what constitutes a simple molecular structure.

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.
