Viscosity is attributed to the cohesion of a liquid. Cohesion is the attraction between like molecules. This attraction comes from the type of bonds the molecule has. The thre
…e types are hydrogen bond, dipole force, and London forces. Hydrogen bond- strongest type of intermolecular bond. Results from an O-H, N-H, of F-H bond. This is because the pulls are so strong by Oxygen, Nitrogen, and Fluorine on Hydrogen that it creates an almost ionic bond. Dipole forces- next strongest type of IMF. results from unequal sharing in a bond. London forces- weakest type of IMF. results from slight polarization in otherwise nonpolar molecules. (MORE)
