Dihydrogen monoxide parody oxygen atom. Literally, the term "dihydrogen monoxide" means "two hydrogen, one oxygen", consistent with its molecular formula: the prefix "" in "dihydrogen" means "two", the prefix "" in "monoxide" means "one", and an oxide is an oxygen atom attached to another atom in an ionic compound. Using chemical nomenclature, various names for water are in common use within the scientific community. Some such names include "hydrogen oxide", as well as an alkali name of "hydrogen hydroxide", and several acid names such as "hydric acid", "hydroxic acid", "hydroxyl acid", and "hydroxilic acid". The term "hydroxyl acid" used in the original text
Dihydrogen complex agostic interaction that is displaced by the H. In other cases, H will displace anionic ligands, sometimes even halides. Treatment of chlorobis(dppe)iron hydride with sodium tetrafluorborate under and atmostphere of hydrogen is one example: Many metal hydrides can be protonated to give dihydrogen complexes: In such cases the acid usually is derived from a weakly coordinating anion, e.g., Brookhart's acid. In 1984, Kubas et al. discovered that the addition of H to the purple-colored species M(CO)(PR) gave a yellow precipitate of mer-trans-M(CO)(PR)(H) (M = Mo or W; R = cyclohexyl, iso-propyl). This result rapidly led to the discovery of a
