(a)
Interpretation: To specify the absorptions which are associated with the carbon-carbon double bond and the hydrogen linked to the third carbon atom.
Concept Introduction: The spectroscopy which includes the interaction of infrared radiation with matter is known as IR spectroscopy. It comprises various techniques, related to absorption spectroscopy. IR spectroscopy is also used to study and recognizing the chemical substances.
(b)
Interpretation: To assign the various resonances to the hydrogen nuclei of 2-methyl -2-butene in
Concept Introduction: Nuclear magnetic resonance (NMR) is a spectroscopy technique that works on the basis that the nucleus of the atoms absorbs
(c)
Interpretation: To assign the various resonances to the carbon nuclei of 2-methyl -1-butene in
Concept Introduction: Carbon-13 NMR has several merits over proton NMR in terms of its power to explain biochemical and organic structures. Carbon-13 NMR provides information related to the backbone of molecules instead of the periphery. In addition, the chemical shift range for Carbon-13 for most organic compounds is around 200 ppm related with 10 to 15 ppm for the proton.
