摘要: THE molecular configuration of benzil has been the object considerable interest for some time because unusual physical characteristics, such as its large optical rotatory power. Caldwell and Le Fevre1 measured dipole moment in several solvents compared it with that phenanthroquinone, which is planar contains two cis carbonyl groups. From lower (3.5 D) electric these authors concluded molecule must be skew C6H5—C=O halves lie different planes making an angle 90°–100° each other.
