The dipole moment (μ) of HBr (a polar covalent molecule) is 0.784D (debye), and its percent ionic character is 11.6 % . Estimate the bond length of the H−Br bond in picometers. Note that 1 D=3.34×10−30 C⋅m and in a bond with 100% ionic character, Q=1.6×10−19 C.
The dipole moment of the water molecule (H2O)is 6.17 x 10-30 C- m. Consider a water molecule located at the origin whose dipole moment p points in the +X-direction. A chlorine ion (Cl), of charge 1.60 x 10-19 C, is located at 3.00 x 10-9m. Assume that ac is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. Find the magnitude...

Some types of molecules that do not possess an intrinsic electric dipole moment can be given one by an external electric field in a process called charge separation, or polarization. In this process, their internal charge distribution becomes distorted by the field, which results in the region of a molecule on the side in the direction of the field gaining a positive net charge and the region on the other side gaining a negative net charge. Both charges have equal...

Some types of molecules that do not possess an intrinsic electric dipole moment can be given one by an external electric field in a process called charge separation, or polarization. In this process their internal charge distribution becomes distorted by the field, with the result that the region of a molecule on the side in the direction of the field gains a positive net charge, while the region on the other side gains a negative net charge. Both charges have...
