Show hintHide hint
Think about how atomic orbitals interact when they come together to form bonds.
Question 2.
What is the significance of the bond order?
Show hintHide hint
Consider how you calculate bond order based on bonding and antibonding electrons.
3Question 3.
What is a bonding molecular orbital?
- An orbital that contains no electrons
- An orbital formed by the overlap of atomic orbitals in phase
- An orbital with a nodal plane
Show hintHide hint
Consider how orbitals align during bonding.
4Question 4.
True or False: Antibonding molecular orbitals increase the stability of a molecule.
- True
- False
Show hintHide hint
Think about how these orbitals affect electron distribution.
Question 5.
