Furthermore, the uneven charge distribution makes them more reactive in certain chemical environments, as the partial charges can attract or donate electrons more readily than nonpolar species. Role of Lone Pairs and Bond Angles The presence of the lone pair is the defining feature that creates the asymmetry essential for polarity.
How Lone Pair Geometry Defines Seesaw Polarity
Vector Addition of Dipole Moments Individual bonds between the central atom and surrounding atoms are polar if there is a difference in electronegativity. In the seesaw structure, the asymmetrical placement means the dipoles do not oppose each other equally.
The vector addition results in a net dipole moment pointing toward the lone pair side of the molecule. The introduction of the lone pair distorts these angles slightly; the axial bonds bend away from the equatorial plane, and the equatorial bonds adjust to accommodate the extra electron density.

In a perfect trigonal bipyramid, bond angles are 90° and 120°. However, molecular polarity depends on the vector sum of these individual bond dipoles.
