version 1.4 (4.63 KB) by Mazin Mustafa. The electric dipole moment and stereochemistry of 2 : 5-dibromo-1 : 4-di-tert.-butylbenzene Helmer Kofod , Lovraj Kumar and L. E. Sutton Abstract Based on new line intensity measurements collected from the literature, the effective dipole moment parameters of acetylene have been found for the 100, 7.7, 1.4, 1.3, 1.2 and 1 μm spectral regions by least-squares fittings. 6).These results, together with published data for 1,4-diacetylbenzene, yield information on the preferred conformations of 1,4-diformyl- and 1,4-diacetyl-benzene. I won't go on for longer because this is getting quite long, but that's the general idea. Why does NH 3 ( 1.4 D) have a larger dipole moment than NF 3 (0.24 D)?. Polar molecules have dipoles, one end has a slightly positive charge, the other a slightly negative charge due to a difference in electronegativities between the atoms in the molecule.
