differentiate between gas chromatography and super critical fluid chromatography
Differentiating between reactants and products using gas chromatography, infrared spectroscopy, and mass spectrometry: I am having trouble figuring out how you would tell the difference between the reactant and products using each of the techniques below. Please explain and answer completely. How would you differentiate between 2-methyl-cyclohexan-1-ol and the three alkene products by each of the following types of data: (a) Gas chromatography (GC) (b) Infrared spectroscopy (IR) (c) Mass spectrometry (MS) IN HO-P-OH OH phosphoric acid .o. Heat 1-methylcyclohex-1-ane...
