Answer:
D) Tetrahedral
Explanation:
Hello,
Tetrahedral is a molecular shape that turns out when four bonds and no lone pairs around the central atom in the molecule. The bonded atoms to the central atom lie at the corners of a tetrahedron with 109.5° angles between them. The molecules with an tetrahedral electron pair geometries have [tex]sp^3[/tex] hybridization at the central atom. For instance, both ammonium ion ([tex]NH_4^+[/tex]) and methane ([tex]CH_4[/tex]) have a tetrahedral molecular geometry.
Best regards.
