Chapter 8, Problem 8.29E

Interpretation Introduction

Interpretation:

The strongest and weakest interaction has to be given.

Concept introduction:

Ionic interaction:

Ionic interactions arise from electrostatic attraction between two groups of opposite charge.  These bonds are formed between positively charged and negatively charged ions.

Dipole-Dipole interaction:

Dipole-Dipole interactions result when two dipolar molecules interact with each other through space.  When this occurs, the partially negative portion of one of the polar molecules is attracted to the partially positive portion of the second polar molecule.  This type of interaction between molecules accounts for many physically and biologically significant phenomena such as the elevated boiling point of water.

Hydrogen bond:

A hydrogen bond is a partial intermolecular bonding interaction between a lone pair on an electron rich donor atom, particularly the second-row elements nitrogen, oxygen and fluorine, and the antibonding orbital of a bond between hydrogen and a more electronegative atom or group.

Non-polar hydrophobic effect:

The tendency of nonpolar molecules in a polar solvent (usually water) to interact with one another is called the hydrophobic effect. The interactions between the nonpolar molecules are called hydrophobic interactions.
