Predict the approximate molecular geometry of a BF⁻₄ ion.
Match the Molecular Geometry with the number of nonbonding
electrons pairs that creates it. Thank you!
An atom with a steric number of 4 has a tetrahedral electron-pair geometry. If some of the electron groups are nonbonding electrons, the molecular geometry (which only considers atoms) will be different. For a tetrahedral electron-pair geometry, match the molecular geometry with the number of nonbonding electron pairs that creates it. Leave incorrect answers where they are on the left.
