      give each carbon atom four bonds

      This means that the LONE PAIRS that are left off/assumed are only for NON-Carbon atoms (like Oxygen)... unless there is a charge, which alters the # of lone pairs.

      SO, when drawing from a Molecular Formula, DRAW ALL HYDROGENS necessary to give Carbon 4 Bonds. NO LONE PAIRS are assumed are Carbons!
