Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. According to VSEPR theory, what is the molecular geometry of a molecule with two bonding pairs and two lone pairs around the central atom?
Linear
Trigonal planar
Bent
Tetrahedral
2. Which of the following molecules exhibits sp3 hybridization around its central atom?
CO2
BF3
CH4
HCN
3. The unequal sharing of electrons between two atoms in a covalent bond results in a bond.
4. forces are attractive forces between molecules, not within them.
5. Describe the key principles of VSEPR theory and how it helps predict molecular geometry.
6. Explain the difference between sigma (σ) and pi (π) bonds, and how they relate to single, double, and triple bonds.
Match the term on the left with its description on the right.
7. Dipole-dipole forces
a. Found in all molecules, weakest intermolecular force
8. Hydrogen bonding
b. Occur between polar molecules
9. London dispersion forces
c. Strongest intermolecular force, involves H bonded to N, O, or F
10. A molecule with a tetrahedral electron geometry is always nonpolar.
True
False
