How might you distinguish compounds by IR spectroscopy? By NMR spectroscopy? - You can distinguish these compounds by IR spectroscopy by analyzing the signals. Each signal represents functional groups, which can help you identify the compound. NMR spectroscopy helps to distinguish the compounds because it tells you how many hydrogens are present. It also tells you how shielded it is and the chemical shift. What does "reflux" mean? - Reflux is when the condenser is recondensing the vapor tha...
