(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 functional groups. The theory on which IR spectroscopy works is that absorption specific
(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.
