The correct statements from the following are : (A) Tl ³⁺ is a powerful oxidising agent (B) Al ³⁺ does not get reduced easily (C) Both Al ³⁺ and Tl ³⁺ are very stable in solution (D) Tl ⁺ is more stable than Tl ³⁺ (E) Al ³⁺ and Tl ⁺ are highly stable Choose the correct answer from the options given below :

Step-by-step solution

(i) True, T ⁺ is more stable than T ³⁺ , due to inert pair effect. So T ³⁺ is a powerful oxidising agent. (ii) True, E _ Al ^ 3+/ A 1 ^0=-1.66 ~V . So it is difficult to reduce A ³⁺ . So A ³⁺ is highly stable. (iii) False, as T ³⁺ is unstable (iv) True, T ⁺ is more stable than T ³⁺ (v) True, A ³⁺ and T ⁺ are highly stable
