Here is todays chemistry challenge problem! An organic compound was analyzed and determined to contain 54.55 percent carbon, 9.09 percent hydrogen, and 36.36 percent oxygen. If molar mass of this compound is approximately 264.0 g/mol, what is its molecular formula? (If a molecule of the compound contains 3 carbon atoms, 4 hydrogen atoms, and 1 oxygen atom, your answer would be: C3H4O i.e. omit any 1's in the formula.)

Well my bio teacher told me that if a compound has 2 or more carbon atoms, then it is organic. Therefore, she said that something like methane wouldn't be organic. However, I've been searching around the internet for a formal definition, and I've come up upon people saying that all an organic compound needs is carbon bonded with hydrogen or something of that nature. Thus methane would be organic? So i just want to clarify on what makes a compound organic. If just by looking at its formula, how can you determine whether the molecule is organic or not?

What organic compound is this: -white crystalline solid -solubility class N or neutral compound -contains oxygen -contains a benzene ring -does not contain nitrogen, sulfur or halogens -has a melting point of 48.5 degrees Celsius It may be hard to pinpoint the exact compound but at least a list of possible compounds may be helpful. Thanks!
