Polymer and Hydrogen Bonds

Background Worksheet

Feel free to also use your chemistry text.

1. Define in one or two sentences the following terms:

Covalent Bond- (Use the term "stable electron configuration")

Ionic Bond- (Use the term "electrostatic attraction")

Hydrogen Bond- (Use the term "electrostatic attraction")

2. What are the three kinds of atoms that when covalently bonded with hydrogen can result in a hydrogen bond between neighboring molecules?

3. Depict the hydrogen-bonding between two ammonia molecules and between one ammonia molecule and one water molecule.

4. What is meant by the term "bond disassociation energy"?

5. Describe the continuum between a nonpolar covalent bond, a polar covalent bond, and an ionic bond. While describing this continuum explain what atomic property determines the nature of a chemical bond. Also be sure to give specific examples.
