Which of the following complex show a tetrahedral geometry?
Correct answer: B. [Cu(CN)4)-2
- A. [Fe(CO)5)
- B. [Cu(CN)4)-2
- C. [Au(Cl)4]-
- D. [Pt(NH3)4]+2
Explanation
[Cu(CN)4]-2 has a tetrahedral geometry. The four cyanide (CN-) ligands are arranged symmetrically around the central copper (Cu) ion, forming a regular tetrahedron.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
