These structures can also be classified as (*) covalent or ionic.
One type of these structures forms between two dipoles and causes water's high melting point. Another type of these structures cannot twist, due to p-orbital overlap; that type exists in sp2 ["s p 2"] hybridized molecules as a "double" type. These structures can also be classified as (*) covalent or ionic. For ten points, name these attractive structures that hold atoms together within molecules.
