Is there any clever way to draw a molecule with a peroxide group (like OOH, and not O–O–H), which would be recognized as a functional group and not like text?
In MarvinSketch, you can create a SuperatomSgroup ( https://docs.chemaxon.com/display/docs/Abbreviated+groups+-+Superatom+group ) from the relevant part of the structure and name it as OOH. Please see the attached MRV, you can contract and expand the group from the context menu. If you like this solution, we can consider to add this group to our default abbreviation list. What do you think?
