determining dipole

[Isabelle Huerta 2I]

Hi,

I was wondering, what factors can be used when considering the magnitude and direction of a dipole moment?

Thanks.

Hi.

When considering the magnitude and direction of a dipole moment, factors to be taken into consideration are electronegativity difference, bond type, and molecular geometry. A dipole moment occurs when there is an unequal among of electrons amongst a covalent bond. A greater electronegativity difference between two atoms results in a more polar bond and therefore a larger dipole moment. As for molecular geometry, an asymmetrical molecule in addition to polar bonds is likely to have a net dipole moment.
