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 answer from the option given below :
Ti⁴⁺ is colourless due to d⁰ configuration.
∴ Statement I is correct.
La³⁺, Yb²⁺, Lu³⁺, Ce⁴⁺, Ac³⁺ & Lr³⁺ all are diamagnetic. ∴
Statement II is correct.
