Question

Which of the molecules below must be shown with resonance structures? I. C2H2 II. CO III. CO2

I only

I and III only

II only

none of the above molecules require resonance structures

Answer 1

The answer is I and III only; resonance structures occur when there are: 4 atoms, 4 bonds and 3 atoms, 3 bonds

Answer 2

The molecules must be shown with resonance structures will be I and II only.

What is resonance structure?

The electronic bonding of a particular polyatomic species, containing partial bonds as well as fractional charges, is described by resonance structures, which are just a collection of two or even more Lewis structures.

What is molecules?

One or even more atoms make up molecules.

Whenever an atom close to a double bond or even a lone pair does have a single bond, a molecule could have resonance structures. The molecules must be shown with resonance structures will be I and II only.
