Hybridization and Valence Bond Theory (U1)
4 important questions on Hybridization and Valence Bond Theory (U1)
When does covalent bond occur?
- When two 1/2 filled (singly occupied) orbitals overlap
- ea. e- has ability to roam the entire region of ea. Orbital
Name types of sigma bonds
- S-s --> Ex: H2
- s-p --> Ex: HCl
- p-p --> F2
- s-sp --> CH4
What is a pi (⨅) bond
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
When is it possible to have a pi bond?
- When sigma σ is present (1st) btwn bonded nuclei (pulls them together so ⨅ bond can form
- when atoms have p orbitals containing only lone e-s (singly occupied unhybridized p)
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
