Homework Help: chemistry

On complete oxidation, one mole of an organic compound produced four moles of water. Which one of the following substances could it be?

CH4
C2H6
C3H7OH
C4H10

So I added O2 to each of these compounds, but I must be doing something wrong because I can't get 4 moles of water. Help? Thanks.

products: 4H2O + XCO2

so you know H is at least 8 in the water, and to get CO2 (required, it has to be greater).
so start with C4H10+ ?O2>>4H2O+ X CO2 Which has CxH8 in it?

only one fits.

C3H7OH right?
