Choose the answer which best denotes the electronic orientation (electronic geometry) of the water molecule.
Ans. D This question is a bit tricky. Many students will quickly select angular as the answer. But you have to be careful. The question is not asking for the molecular geometry of water. It is actually asking for the electronic orientation or electronic geometry of water which is tetrahedral. The four electron pairs (two bonded pairs and two lone pairs) of the water molecule result in a tetrahedral geometry. Moreover, Choices A and B are essentially the same. If one is not correct, the other cannot be correct either.
