Why is IR spectroscopy better than [tex]^1H[/tex] NMR spectroscopy for determining if any starting material remains after the reduction reaction?

(Note: A copy of the [tex]^1H[/tex] NMR spectrum of 2-methylcyclohexanone is posted to Blackboard for reference.)

Final answer:

IR spectroscopy is preferred over 'H NMR spectroscopy for determining remaining starting material post-reduction due to its ability to identify functional groups accurately.


Explanation:

IR spectroscopy is better than 'H NMR spectroscopy for determining if any starting material remains after a reduction reaction because IR spectroscopy is particularly useful for identifying functional groups. For instance, if we convert cyclohexanone to cyclohexanol, comparing the IR spectra of the starting material and the product would reveal changes, such as the disappearance of the ketone signal and the appearance of an alcohol signal.
