Which of the following species is not tetrahedral?

Options

  1. ACH ₄
  2. BSF ₄
  3. C+ N H ₄
  4. DSiCl ₄

Correct answer

B. SF ₄

Step-by-step solution

Analysis of Molecular Geometry To determine which species is not tetrahedral, the hybridization and VSEPR geometry of each molecule or ion are analyzed. A species with a steric number of 4 and no lone pairs on the central atom exhibits tetrahedral geometry. For CH ₄ , the central carbon atom has steric number 4 with sp^3 hybridization and tetrahedral geometry. For SF ₄ , the central sulfur atom has valence electrons = 6, bonding pairs = 4, and lone pairs = 1, giving steric number 5 and sp^3d hybridization. The geom
