Imfa observed in water molecules
WitrynaAn electric monopole is a single charge, while a dipole is two opposite charges closely spaced to each other. Molecules that contain dipoles are called polar molecules and are very abundant in nature. For example, a water molecule (H 2 O) has a large permanent electric dipole moment. Its positive and negative charges are not centered at the ... WitrynaMelting Points in Organic Chemistry. The melting point of a compound is the temperature at which the solid phase transitions into the liquid phase at a standard pressure of 1 atmosphere. The melting point of a compound is a physical property, like solubility, density, color, and electronegativity that can be used to identify a compound.
