10 Questions
Which type of overlapping of atomic orbitals forms a σ bond?
Head-to-head overlap
What type of combination of atomic orbitals may form a σ bond?
s-s, s-p, and p-p orbitals
Which type of molecular orbital is more stable than both antibonding molecular orbitals and parent atomic orbitals?
Bonding orbital
What is the electron density like in antibonding molecular orbitals?
Low
What is the main difference between bonding and antibonding orbitals?
Bonding orbitals contribute to the shape of the molecule, but antibonding orbitals do not.
In molecular orbital theory, what type of bond is formed when atomic orbitals intersect in a sideways positive direction perpendicular to the internuclear axis?
Pi (π) bond
How are sigma (σ) and pi (π) bonds formed in relation to each other?
Sigma bonds are formed first, followed by pi bonds
What are the characteristics of pi* (π*)-orbitals in molecular orbital theory?
Contain two nodal planes, one through the bonding axis and the other between nuclei
What is the bond order for carbon (C2) based on its molecular orbital energies?
2
What determines the stability of a resulting molecule in molecular orbital theory?
The energy differential between the lower and higher energy orbitals
