Oxygen is prevalent in the atmosphere as gaseous diatomic oxygen (O2), in the hydrosphere as water (H2O), and the geosphere as oxides of various metal and metalloid elements. Oxygen is prevalent in biological molecules and commercial compounds. Examples of the latter include phenol, n-octanol, methylethylketone, and methyl-t-butyl-ether (MTBE).
