Read each question carefully and provide detailed answers or select the best option. Show all your work for calculations.
1. What is a covalent bond? Describe the primary mechanism by which a covalent bond forms between two atoms.
2. Which of the following best describes a nonpolar covalent bond?
Electrons are transferred from one atom to another.
Electrons are shared unequally between two atoms.
Electrons are shared equally between two atoms.
Atoms lose or gain electrons to form ions.
3. Consider the illustration below. What type of covalent bond is depicted?
Single covalent bond
Double covalent bond
Triple covalent bond
Ionic bond
4. The VSEPR theory helps predict the of molecules based on the repulsion between electron pairs.
5. A molecule with polar bonds can be nonpolar overall if its molecular geometry results in a distribution of electron density.
6. Draw the Lewis structure for the water molecule (H2O). Indicate any lone pairs and predict its molecular geometry and polarity. Explain your reasoning.
7. All molecules with polar covalent bonds are polar molecules.
