Question

Among the following pairs of ions, the lower oxidation state in aqueous solution is more stable than the other in:-

पर्याय

• Ti⁺, Ti³⁺

• Cu⁺, Cu²⁺

• Cr²⁺, Cr³⁺

• V²⁺, Vo²⁺

Answer 1

Ti⁺, Ti³⁺ 

Explanation:

Because only the valance 6p¹ electron is removed, Ti⁺ is more stable than Ti³⁺ due to the inert pair effect.
