Read each question carefully and provide your best answer. Show all work for calculations.
1. Which of the following describes a nonpolar covalent bond?
Electrons are shared unequally.
Electrons are transferred completely.
Electrons are shared equally.
The bond forms between a metal and a nonmetal.
2. What is the approximate electronegativity difference that typically indicates a polar covalent bond?
0 - 0.4
0.5 - 1.7
1.8 - 3.0
Greater than 3.0
3. The ability of an atom to attract electrons in a chemical bond is called .
4. In a polar covalent bond, the atom with the higher electronegativity will have a partial charge.
5. All molecules containing polar bonds are polar molecules.
True
False
6. A bond between two identical atoms is always nonpolar.
True
False
7. Explain the difference between a polar covalent bond and an ionic bond in terms of electronegativity difference and electron sharing/transfer.
8. Consider the molecule CO2 (carbon dioxide). Although it contains polar C-O bonds, the molecule itself is nonpolar. Explain why.
9. The image below illustrates a type of chemical bond. Based on your understanding of bond polarity, identify the type of bond shown and explain your reasoning.
