A well-known chemist, Havno Szents, has heard you apply the rules for predicting molecular geometry to water; you have proposed a bent geometry for this compound. Dr. Szents is unconvinced by your arguments and continues to propose that water is a linear molecule.

He demands that you debate the issue with him before a distinguished academy. You must therefore come up with experimental data that will prove to an objective body of scientists that water indeed has a bent geometry. Explain why the dipole moment of water, 1.84 D, could be used to support your case.
