**********************************
$<b>Valence bond theory is a chemical bonding theory that explains the bonding between two atoms is caused by the overlap of half-filled atomic orbitals. The two atoms share each other's unpaired electron to form a filled orbital to form a hybrid orbital and bond together.$

☆☞$\mathcal\red{\underline{\underline{Limitations\:to\:Valence\:Bond\:Theory}}}$

✔♣Failure to explain the tetravalency exhibited by carbon.

✔♣No insight offered on the energies of the electrons.

✔♣The theory assumes that electrons are localized in specific areas.

Answer 2

hi dear....

Definition: VALENCE BOND THEORY is a chemical bonding theory that explains the bonding between two atoms is caused by the overlap of half-filled atomic orbitals. The two atoms share each other's unpaired electron to form a filled orbital to form a hybrid orbital and bond together.

Examples: Sigma and pi bonds are part of valence bond theory.

Limitations of Valence Bond Theory


1) It fails to explain the tetravalency of carbon.

2) this theory does not discuss the electrons’ energies.

3) The assumptions are about the electrons being localized to specific locations...



hope it helps....
