15. Solving a chemistry problem

148. Explain the experimentally established structure of a molecule or ion using the method of valence bonds. Indicate the type of hybridization of the orbitals of the central atom, depict the overlap of the orbitals and determine if this particle is polar.
Attention! The type of a molecule is generally written as ABm, En, where A is the central atom, B are the terminal atoms, and E are lone pairs of electrons. The presence of a lone pair of electrons in a molecule is designated as B*. In the case of a trigonal bipyramid (sp3d hybridization), the lone pairs of electrons are located in the equatorial plane, while in the case of an octahedron (sp3d2 hybridization), they are in axial positions.
