The proton NMR spectrum of a saturated hydrocarbon shows a single absorption line at 1.42 ppm with respect to TMS at room temperature. The area of the line is equivalent to 12 protons. Solely based on this observation, what are the tentative inferences you can draw about the nature of the hydrocarbon? (a) It is a pure compound i.e. there are no impurities present. (b) More than conformation of the molecules may be present and they are undergoing rapid interconversion. (c) The hydrocarbon is cyclohexane (d) All of the above
