Concept explainers
(a)
Interpretation:
The plausible Lewis structure of FNO should be predicted.
Concept introduction:
Lewis structure represents the distribution of electrons by an individual atom in a molecule. The molecular structure is a 3-dimensional representation of bond pairs around the central atom. It is also known as molecular geometry.
(b)
Interpretation:
The geometric shape of FNO should be predicted.
