CH3OH2

CH3OH2 is not a recognized chemical formula for a stable molecule. The notation suggests a methyl group (CH3) bonded to a protonated methanol species. Protonated methanol, CH3OH2+, is a carbocation that exists as an intermediate in certain chemical reactions, particularly in acidic environments. In this species, the oxygen atom of methanol gains a proton, resulting in a positive charge. This protonation makes the hydroxyl group a better leaving group, facilitating reactions such as nucleophilic substitution. However, CH3OH2 as a neutral, stable molecule is not chemically plausible under standard conditions. The extra hydrogen atom would typically be lost as a proton, or the molecule would undergo rearrangement or decomposition. If encountered in a chemical context, it likely refers to the transient cation CH3OH2+ or a typo.
