Hydrogen bonding between paraffinwax, cholesterol, naphthalene with phenol is studied in carbon tetrachloride by using the FTIR spectroscopic method. Utilizing the Nash method, the formation constant (K) of the 1:1 complexes is calculated. Using the K value, the free energy change (∆G) is also calculated. The calculated formation constant and free energy change values vary which suggests that the proton donating ability in the order: paraffin wax ˂ cholesterol ˂ naphthalene.
