Question
The correct statements from the following are : (A) TI3+ is a powerful oxidising agent (B) AI3+ does not get reduced easily (C) Both AI3+ and TI3+ are very stable in solution (D) TI+ is more stable than TI3+ (E) AI3+ and TI+ are highly stable (A) (A), (C) and (D) only (B) (B), (D) and (E) only (C) (A), (B), (D) and (E) only (D) (A), (B), (C), (D) and (E)
Answer: C
💡 Solution & Explanation
(A) True, Ti+ is more stable than Tl3+ due to inert pair effect. So, Tl3+ is a powerful oxidising agent. (B) True, Al / Al3 E = –1.66. So it is difficult to reduce Al3+. So Al3+ is highly stable. (C) False, as Tl3+ is unstable. (D) True, Tl+ is more stable than Tl3+ True, Al3+ and Tl+ are highly stable.
