Question
The coordination environment of Ca2+Ca2+ ion in its complex with EDTA4−EDTA4− is :JEE Main 2024 (09 Apr Shift 2)AtetrahedralBtrigonal prismaticCoctahedralDsquare planar
Solution
The coordination environment of Ca2+ ion in its complex with EDTA4− is octahedral. Therefore, the correct answer is C. Octahedral.
Here's why:
EDTA4- is a hexadentate ligand, which means it can form six bonds with a central metal ion. In the case of the Ca2+ - EDTA4- complex, the EDTA4- ligand forms six coordinate bonds with the Ca2+ ion, resulting in an octahedral geometry.
