How can you distinguish polyethylene from polypropylene based ontheir spectra? Give specific differences both in the C-H region andin the C-C region. What functional group is this attributed to inits structural formula? 7. Ignoring the intensities and consideringonly the number of peaks in the C-H region, compare the spectra ofpolyethylene and polypropylene with polyvinyl chloride. Formulate ahypothesis relating the C-H region of the spectrum to the polymerstructure (specifically, consider the hydrogen atom environments).Support your hypothesis with evidence from these threepolymers.
