How can you distinguish between a primary amine and a secondary amine using IR spectroscopy? 18. Describe the relative size of the M and M 2 peaks for the alkyl chloride, CHiCH,CI.

Solution

Q no 15:-

Infrared Spectroscopy is used to measures
the vibrations of bonds, and based on this it is possibly used to determine the functional groups.
Hence option (a) is correct.
