These two remaining products can be separated by distillation, the alcohol having the higher boiling point because of hydrogen bonding. 20-7 The has a characteristic IR absorption: a broad peak from 3400-2400 cm-I, with "shoulder" around 2700 cm-I. The carbonyl stretch at 1695 cm-I is a little lower than the standard 1710 cm-I, suggesting conjugation. The strong alkene absorption at 1650 cm-I also suggests it is conjugated.
