Lesson Worksheet: Molecular Orbital Theory Chemistry • 10th Grade
In this worksheet, we will practice describing the shapes, energies and electron occupancies of bonding, nonbonding, and antibonding molecular orbitals.
Q1:
An sp2 hybridized atom in a molecule forms bonds to three other atoms of the same element. There are no other bonds in the molecule. Which of the following statements is true?
- AThe dipole moment of each bond is zero.
- BThe three bonds contribute equally to each bonding molecular orbital.
- CAll of the bonds are partial double bonds.
- DThe three bonds contribute equally to each bonding energy level.
- EThe molecular bonding orbitals have the same energy.
Q2:
Which of the following electronic transitions do alkanes exhibit?
- A to
- B to

- AUnpaired electrons in antibonding orbitals
- BPaired electrons in antibonding orbitals
- CPaired electrons in nonbonding orbitals
- DUnpaired electrons in nonbonding orbitals
- EUnpaired electrons in bonding orbitals
