For each of the following molecules, write a Lewis structure, predict the molecular structure (including bond angles), and give the expected hydra orbitals for sulfur d. S2O3^2-

Draw the best Lewis dot structure for BrO₄⁻, being sure to give the electronic geometry, molecular geometry, hybridization of the central element, polarity, and bond angle around the central element.

1A2: Define electron pair domain (EPD), count EPDS on building blocks, and use EPD knowledge to determine 3D geometry and bond angles of a tetrahedral, trigonal planar, linear building block. For the indicated atoms (look for the arrows) in each of the given structures: (a) state how many EPDs are present; (b) Label tetrahedral atoms with "TET," trigonal planar atoms with "TP," and linear atoms with "LIN;" (c) Identify one (1) indicated atom in each structure for which resonance structures bring a change in the number of EPDs from 4++3/3+4 or 3+2/2+3. A resonance structure must be reported to justify your reported EPD changes. H₂C CH3 --С HO 1 Br -CH3 CH3 CI H₂C N CH3 CH3 он о
