Would IR spectra of all the products be useful in differentiating the isomeric alkenes? Consider the NMR spectra below. To which dehydration product does it belong (it was a dehydration of cis or trans 2-methylcyclohexanol)? Explain and give an assignment for the 13C-NMR; be sure to assign the weak peak at ~150 ppm. Ignore the solvent peaks at 77 ppm.
