JEE Main 2026 Chemistry question
is a paramagnetic complex. Identify the INCORRECT statements about this complex. A. The complex exhibits geometrical isomerism. B. The complex is white in colour. C. The calculated spin-only magnetic moment of the complex is 2.84 BM. D. The calculated CFSE (Crystal Field Stabilization Energy) of Ni in this complex is . E. The geometrical arrangement of ligands in this complex is similar to that in . Choose the correct answer from the options given below :
Answer: (2)
Solution
It's tetrahedral (paramagnetic Ni²⁺, d8). Tetrahedral doesn't show geometrical isomerism (A incorrect). Complex is blue not
