Physics 2212: Matter and Interactions Chapter 13: dipole moments Molecular Dipole Moments Even though the total charge on a molecule can be zero, arrangement of the charges are often such that there is an associated dipole moment. An electric dipole in an external electric field is subjected to a torque τ = pE sin θ, where θ is the angle between p and E. The torque tends to align the dipole moment p in the direction of E. The potential energy of the dipole is given by U e = −pE cos θ, or in vector notation … The contents of this page can freely be shared if cited as follows: NOTICE: Due to scheduled maintenance at our Gaithersburg facility, this site will not be available from 7:00 pm until midnight EST on Monday December 28.

Feb., 1945 DIPOLE MOMENTS OF CATECHOL, RESORCINOL AND HYDROQUINONE 323 reported in the literature as equal to 2.16 D.21‘ Based on that value, good agreement has been claimed2.6 with the moment of 2.21 D calculated by Fuchs and Wolf on the assumption of complete freedom of rotation around the 0 to C bond con- necting the polar groups to the ring. In cyclohexane, the carbon attached to Chlorine is Sp3 hybridised. (In this context, “close” means that the distance d between the two charges is much, much less than the distance of the field point P, the location where you are calculating the field. The above chemical formula is the basis of stoichiometry in chemical equations, i.e., the calculation of relative quantities of reactants and products in chemical reactions. (Hide this section if you want to rate later). When Carbon is... Sp3 hyridised, one Chlorine can be Above the benzene ring plane and second Chlorine can be on he plane.
