Solved: Rank the following compounds from highest dipole

Solution 63P :

Step 1 of 6:

Here, we have to rank the following compounds from highest dipole moment to lowest dipole moment. First, let’s see what is a dipole moment and then we shall rank them.

Dipole moment is a measure of the polarity of the molecule, i.e it is a measure of the separation of two electrically opposite charges, i.e The difference in the electronegativity of the atoms or ions causes the dipole moment. Larger, the difference in electronegativity, larger is the dipole moment. Also the distance between the separation of charges decides the size of the dipole moment.
