# Peroxide without hydrogen [closed]

How come we always see hydrogen peroxide and never peroxide by itself. Is there such a thing as peroxide ? Does this exist in nature? Why is hydrogen always associated with it? Please note: First semester chem student so new to all this. Thanks!

• Are you interested in how abundant free $\ce{O2^{2-}}$ in nature, or is there any hydrogen-free peroxides at all? – andselisk Jul 20 '17 at 6:26
