Is C3H7O2 an organic molecule? I think it's an anion and not a molecule. If it is an organic molecule please help me with the structure. My exam paper states that it is an organic molecule.

Sorry for the poor drawing attempt, just thought I would quickly do a sketch on paint.
Was quick but by no mean neat... =(

But we would have five bonds surrounding the middle carbon.

Sorry about that.

Define organic:
Containing C-C bond
Containing C-H bond
So it is organic

The main point here is we don't have a molecule.

If you want all your atoms in their normal oxidation state and be a neutral molecule then it's impossible
Cyclic structure incorporate maximum of 6 Hydrogen
On the other hand linear structure either incorporate 6 or 8 Hydrogen
Searched the molecule in google and this is the only possible scenario, where one oxygen only form 1 bond

A solution of 1.781g of an organic molecule C3H7O2 in 100g of benzene freezes at a temperature 0.606K below the melting point of pure benzene. The cryoscopic constant for benzene is 5.11 K molal-1. Calculate the molecular weight of the molecule in benzene and comment on your result. State any assumptions that you have made and suggest a structure for the dissolved molecules.
Molecular weight of C3H7O2 is 150.18g/mol
C3H7O2 has a molecular weight of 75g/mol
This answer gives double the molar mass we expected i.e two molecules form a single particle in solution in benzene. But what about the structure? Can you think of a possible structure?

What is a molecule? IUPAC says:
An electrically neutral entity consisting of more than one atom (n > 1). Rigorously, a molecule, in which n > 1 must correspond to a depression on the potential energy surface that is deep enough to confine at least one vibrational state.
What is an organic compound? Wikipedia says:
An organic compound is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon. For historical reasons discussed below, a few types of carbon-containing compounds, such as carbides, carbonates, simple oxides of carbon (such as CO and CO2), and cyanides are considered inorganic...
So, is it organic AND a molecule?
Wiki suggests it is organic, but to be considered a molecule, it must be neutral, i.e. NOT C3H7O2+. To me, it looks like it must be a radical, which fits the definition of an organic molecule. Can radicals not be molecules? IUPAC suggests they can, I understand.
