The carbonyl group, C=O, has a large dipole moment and thus an intense stretching vibration whose peak generally appears from 1900 to 1600. When an aromatic ring is attached to a carbonyl carbon, the C=O stretching peak position is lowered by about 30 cm-1 because of a phenomenon known as conjugation. … See more A methyl ketone is a structure where one or more of the substituents on the carbonyl carbon is a methyl group.
