All rights reserved. Due to the arrangement of the bonds in molecules that have V-shaped, trigonal pyramidal, seesaw, T-shaped, and square pyramidal geometries, the bond dipole moments cannot cancel one another. In contrast, the H2O molecule is not linear (Figure \(\PageIndex{2b}\)); it is bent in three-dimensional space, so the dipole moments do not cancel each other.
