cf. C.A. 44, 7601e. The dipole moments of pentaerythritol tetrabromide (I), tetraiodide (II), and tetranitrate (III) in benzene and in dioxane were determined For both I and II, the dipole moment was zero; this indicates that there is no free rotation about the C-C bond. In the case of III the moment was 2.5 D.; this indicates free rotation about the C-O bond in the nitrate. It is concluded, therefore, that the shortening of the C-O bond, observed in the crystal, cannot be due to a high degree of double-bond character.
