Question 1.
What is bond order?
Show hintHide hint
Remember Nb is from bonding orbitals while Na is from antibonding orbitals.
Question 2.
Define diamagnetic.
Show hintHide hint
Think about the presence of unpaired electrons for the counterpart.
3Question 3.
What determines if a molecule is stable?
- Only Nb
- Only Na
- Nb > Na
- Na > Nb
Show hintHide hint
Focus on bonding vs. antibonding in stability.
4Question 4.
Which type of molecular orbital has a higher energy?
- True
- False
Show hintHide hint
Remember the definitions of bonding and antibonding.
Question 5.
Given the molecules N2, O2, and F2, compare their magnetic properties and bond orders.
Show hintHide hint
Calculate bond orders using Nb and Na and observe unpaired electrons.
Question 6.
Explain why the bond length decreases with increasing bond order, using examples.
Show hintHide hint
Consider the attractive forces acting on the atoms.
