Besides VSEPR and the Kossel Lewis approach, which two theories are listed?
AValence band and molecular orbital
BValence bond and molecular oscillation
CValence band and molecular oscillation
DValence bond and molecular orbital
Answer & Solution
Correct answer: D. Valence bond and molecular orbital
1. Four approaches to bonding are named together.
2. Two of them are Kossel Lewis and VSEPR.
3. The others are Valence Bond Theory and Molecular Orbital Theory.
4. So the answer is valence bond and molecular orbital.
