WebIn organic chemistry, a hydrate is a compound formed by the hydration, i.e. "Addition of water or of the elements of water (i.e. H and OH) to a molecular entity". [3] For example: ethanol, CH3−CH2−OH, is the product of the hydration reaction of ethene, CH2=CH2, formed by the addition of H to one C and OH to the other C, and so can be ...

WebJan 23, 2024 · A delocalized electron is an electron in an atom, ion, or molecule not associated with any single atom or a single covalent bond . In a ring structure, delocalized electrons are indicated by drawing a circle rather than single and double bonds. This means the electrons are equally likely to be anywhere along the chemical bond. WebAug 28, 2024 · A crystal structure is defined as the particular repeating arrangement of atoms (molecules or ions) throughout a crystal. Structure refers to the internal arrangement of particles and not the external appearance of the crystal.
