Witryna4.1 Intermolecular and interatomic forces (ESBMM) Intermolecular forces. Intermolecular forces are forces that act between molecules. You will also recall from the previous chapter, that we can describe molecules as being either polar or non-polar.A polar molecule is one in which there is a difference in electronegativity between the atoms … WitrynaThis creates a partial negative charge on the oxygen end of a water molecule. The hydrogen ends of the molecule develop a partial positive charge. Ethanol is made up of two carbon atoms, six hydrogen atoms and one oxygen atom. Its chemical formula is CH3CH2OH. Ethanol contains a hydroxyl group, which is an oxygen atom bonded to …
