JEE Main 2026 Chemistry question
Given below are two statements: Statement I: The number of pairs among [Ti⁴⁺, V²⁺], [V²⁺, Mn²⁺], [Mn²⁺, Fe³⁺] and [V²⁺, Cr²⁺] in which both ions are coloured is 3. Statement II: The number of pairs among [La³⁺, Yb²⁺], [Lu³⁺, Ce⁴⁺] and [Ac³⁺, Lr³⁺] ions in which both are diamagnetic is 3. In the light of the above statements, choose the correct from the options given below:
Answer: (A)
Solution
Ti⁴⁺ is d⁰ (colourless), so the first pair fails; V²⁺ (d³), Mn²⁺ (d⁵), Fe³⁺ (d⁵) and Cr²⁺ (d⁴) are all coloured, giving
