In AX3, the central atom A forms three single covalent bonds and has two lone pairs. What is the molecular geometry of the molecule? What will be molecular geometry if A has three lone pairs? Why? Predict whether the molecule is polar or nonpolar in both these cases. What type of hybridization will the central atom undergo when A has three lone pairs in the molecule described in (a) above? Can hybridization explain the paramagnetic behavior of molecules? Justify your...
