glucose=polar with the O-H groups and hydrogen bondings
hexane=non-polar
Does anyone know why Glucose is soluble in water but is not soluble in Hexane?

* I had written that water is polar and so is glucose, while hexane is non polar. But I got it wrong.
other choices included; glucose has fewer hydrogens than hexane.
hexane is an organic solvent and glucose is not an organic compound.
compounds that contain oxygen will repel compounds that don't.

None of those other choices fit. Like dissolves like. Glucose has OH groups; water has OH groups. But polarity is the best choice.
? confused. Are you saying none of those choices can be correct?
Those are the only choices to chose from though. I too thought it was about polarity, but as I said, I got it wrong.
The only other one I could maybe go with is the hexane is an organic and glucose is not. I think that is true?

No. It is true that hexane is an organic molecule; however, glucose is an organic molecule, also.

Glucose is C6H12O6; hexane is C6H12 so it can't be this one.
hexane is an organic solvent and glucose is not an organic compound.
Both are organic compounds
compounds that contain oxygen will repel compounds that don't.
I wouldn't buy into this as a general rule. For example, I'm essentially positive that a long-chain alcohol would be soluble in hexane and that would violate the rule. However, of the three choices you have, this one is the closest.
I still agree with the answer by anonymous that it's a case of polarity and hydrogen bonding. Personally I think the oxygen repelling answer is nonsense.

an organic compound is any compound with carbon atoms in it! so hexane and glucose are both organic compounds.
