While this approach does not possess the full and stringent predicting power of quantum mechanical calculations, it allows us to arrive at almost correct geometries (actual deviations from ideal VSEPR angles are generally rather small and can also be foreseen and approximately quantified within a VSEPR framework) and bond multiplicities. This has greatly contributed to the relevance of the Lewis dot formulas, which, as a matter of fact, still constitute a fundamental topic in any General Chemistry teaching course.
