JEE Main 2024 Chemistry question
Match List-I with List-II. List-I (Species): (A) Cr²⁺, (B) Mn⁺, (C) Ni²⁺, (D) V⁺ List-II (Electronic distribution): (I) 3d⁸, (II) 3d³4s¹, (III) 3d⁴, (IV) 3d⁵4s¹ Choose the correct answer from the options given below
Answer: (B)
Solution
Cr²⁺ = 3d⁴ (III), Mn⁺ = 3d⁵4s¹ (IV), Ni²⁺ = 3d⁸ (I) and V⁺ = 3d³4s¹ (II).
