Question

How can we determine the dipole moment of a molecule and compare it

Answer 1

When a mixture of methane and chlorine is exposed to ultraviolet light - typically sunlight - a substitution reaction occurs and the organic product is chloromethane. However, the reaction doesn't stop there, and all the hydrogens in the methane can in turn be replaced by chlorine atoms.

Answer 2

Dipole moment is the approximate value of the difference in the electronegativities of two atoms.Draw dipole moment vectors in the direction of electron shift for each bond in a molecule. Draw the resultant and compare with another. If more electronegative atoms are there in an atom it will have more dipole moment
