Dioxygen difluoride is a compound of fluorine and oxygen with the molecular formula O 2 F 2. It can exist as an orange-colored solid which melts into a red liquid at −163 °C (110 K). It can exist as an orange-colored solid which melts into a red liquid at −163 °C (110 K).
Oxygen difluoride is a chemical compound with the formula OF 2. As predicted by VSEPR theory, the molecule adopts a bent molecular geometry. It is a strong oxidizer and has attracted attention in rocketry for this reason. [5] With a boiling point of −144.75 °C, OF 2 is the most volatile (isolable) triatomic compound. [6]
Oxygen difluoride. A common preparative method involves fluorination of sodium hydroxide: 2 F 2 + 2 NaOH → OF 2 + 2 NaF + H 2 O. OF 2 is a colorless gas at room temperature and a yellow liquid below 128 K. Oxygen difluoride has an irritating odor and is poisonous. [3] It reacts quantitatively with aqueous haloacids to give free halogens:
Oxygen compounds. Water (H 2 O) is the most familiar oxygen compound. The oxidation state of oxygen is −2 in almost all known compounds of oxygen. The oxidation state −1 is found in a few compounds such as peroxides. Compounds containing oxygen in other oxidation states are very uncommon: − 1⁄2 (superoxides), − 1⁄3 (ozonides), 0 ...
Difluoride. Difluorides are chemical compounds with two fluorine atoms per molecule (or per formula unit). Metal difluorides are all ionic. Despite being highly iconic, the alkaline earth metal difluorides generally have extremely high lattice stability and are thus insoluble in water :D. The exception is beryllium difluoride.
Alcohol oxidation. Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters where the carbon carries a higher oxidation state. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form ...
The dioxygenyl ion, O+. 2, is a rarely-encountered oxycation in which both oxygen atoms have a formal oxidation state of + 1 2 . It is formally derived from oxygen by the removal of an electron: O 2 → O+. 2 + e −. The energy change for this process is called the ionization energy of the oxygen molecule.
