Question

Which one of the following has tetrahedral geometry?

विकल्प

• [Fe(CO)₅]

• [CO(NH₃)₆]²⁺

• [NiCl₄]²⁻

• [Ni(CN)₄]²⁻

Answer 1

[NiCl₄]²⁻

Explanation:

The compound [NiCl₄]²⁻ has tetrahedral geometry because nickel(II) forms four bonds with chloride ions in a symmetrical arrangement, resulting in a 3D shape with 109.5° bond angles.
