12. Why do the two methyl groups indicated in the figure below give a single peak integrating for 6 protons rather than two peaks integrating for 3 protons? H3C H3C + .CH3 OH 4-hydroxy-4-methylpentan-2-one OD. The two methyl groups are spin spin coupling with each other. OA. 60MHz NMR have a low resolution so cannot easily resolve the two peaks. B. The molecule is chiral. OC. Both of the methyl groups are in the same chemical environment.
