Question about IR Spectroscopy
Suppose that you are carrying out a dehydrohalogenation reaction on 2-bromo-2,3-dimethylpentane to yield alkenes. Once the reaction is complete and the two elimination products have been isolated into separate vials, how could you use IR spectroscopy to identify which alkene is in which vial?
