The NH3 molecule is polar. Explain how does this offer experimental proof that the molecule cannot be planar?
If NH3 were planar, the NH3 bond dipoles would cancel as well as the molecule would be non-polar. If NH3 were planar, the NH3 bond dipoles would amplify as well as the molecule would be polar. If NH3 were not planar, the NH3 bond dipoles would cancel and the molecule would be non-polar. There is no evidence that can confirm the theory that the molecule cannot be planar.
