Question

Which of the following molecules may be polar: Ar, CO, NH ,, H, XeF, CIF3, O3, CH, F, CH ,, H, O,

Answer 1

VSEPR theory is based on observable electron density rather than mathematical wave functions and hence unrelated to orbital hybridisation,[5] although both address molecular shape. While it is mainly qualitative, VSEPR has a quantitative basis in quantum chemical topology (QCT) methods such as the electron localization function (ELF) and the quantum theory of atoms in molecules (QTAIM).[4]
