Question

What are the weaknesses of Lewis models?

Answer 1

Answer:

Limitations of Lewis structures:

resonance structures and violations of the octet rule (odd electron, hypovalent and hypervalent molecules).

(1) Shapes of simple molecules with “central” atoms.

(2) Configuration: the position of atoms in space about a central atom.
