What intermolecular forces present in ethanol?

The primary intermolecular force present in ethanol is hydrogen bonding. There are three intermolecular forces that occur in covalent compounds: Dipole-dipole forcesoccur when polar molecules are attracted to one another

The periodic table is organized by their chemical reactions and such. The chemical reactions are an effect of the amount of valance electrons an element contains. So basically, the electrons provide the elements energy in any given reaction. And the reactions determine where the element is located on the table.
