(a)
Interpretation:Considering the spectral data for cyclohxene, the absorptions which are associated with the carbon-carbon double bond and the vinylic hydrogen atoms should be specified.
Concept Introduction : The analysis of the interaction of infrared light with a molecule is termed as infrared spectroscopy. The main use of infrared spectroscopy is the identification of
(b)
Interpretation:To assign the various resonances to the hydrogen nuclei that is responsible for them 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 various resonances to carbon nuclei responsible for them in the
Concept Introduction : Carbon-13 NMR has several merits over proton NMR in terms of its power to explainbiochemical and organic structures. Carbon-13 NMR provides information relatedto 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.
