Question

2-Methycyclohexanol is prepared commercially by catalytic hydrogenation of ocresol (2-methylphenol) and consists of a mixture of cis and trans isomers. (Note the spectrum is for the mixture.) (Hint: What do the peaks at 3.05 ppm and 3.75 ppm represent and what does their integration show

Answer 1

The peaks at 3.05 ppm and 3.75 ppm in the spectrum of 2-Methylcyclohexanol represent the hydroxyl protons and the protons on the adjacent carbon atoms, respectively. Integration in NMR spectroscopy shows the relative number of hydrogen atoms represented by each peak.

Step-by-step explanation:

The peaks at 3.05 ppm and 3.75 ppm in the spectrum of 2-Methylcyclohexanol represent the protons attached to the hydroxyl group and the protons attached to the adjacent carbon atoms, respectively.

Integration in NMR spectroscopy refers to the relative number of hydrogen atoms represented by each peak. In this case, the integration would show the ratio of the number of hydroxyl protons to the number of protons on the adjacent carbon atoms.
