Title: Bonding Type by Solubility, Distillation, and Spectroscopy 
Purpose: In this lab, we will study the bonds that form between molecules. We learn about the 
Infrared Spectra and physical properties of molecules to determine what kinds of intramolecular bonds are present within the molecules and what kinds of inter-molecular bonds are 
present between the molecules. 
Procedure: 
There are several different types of bonds – Hydrogen bonds, Polar bonds, and Nonpolar 
substances that form ver...
