* Methane (CH4) is a simple hydrocarbon with four hydrogen atoms bonded to a carbon atom. It's a gas at room temperature.
* Hydroxide (OH-) is a negatively charged ion consisting of an oxygen atom and a hydrogen atom. It's a common component of bases.
Methane is a nonpolar molecule, meaning it doesn't have a significant positive or negative charge. Hydroxide ions are highly polar. These differences in polarity prevent them from forming a stable compound.
What might be happening?
You might be thinking of a related compound called methanol (CH3OH). Methanol is an alcohol where a hydrogen atom in methane has been replaced with a hydroxyl group (-OH).
In summary: Methane hydroxide doesn't exist. The related compound you might be looking for is methanol.
