Title: Bonding and Properties Purpose: Study the infrared spectra and physical properties of molecules to determine what kinds of intra-molecular bonds are present within the molecules and what kinds of intermolecular bonds are present between the molecules. Procedure: 1. Add potassium chloride (ionic) to water in a test tube. Shake tube so potassium chloride dissolves. 2. Add pentate to test tube of water. Shake to see if it dissolves in the water. 3. Add normal propyl chloride to test t...
