Question
Match List-I (Species) with List-II (Hybrid orbitals used by the central atom in their formation) and select the correct answer :<br>List-I<br>(A) Ni(CN)5^3-<br>(B) CuCl5^3-<br>(C) AuCl4^-<br>(D) ClO4^-<br>List-II<br>(1) sp3<br>(2) dsp2<br>(3) sp3d_z2<br>(4) d_x2-y2 sp3
π‘ Solution & Explanation
Step 1: Ligands with higher field strength produce larger splitting (Ξ_o) (I). Step 2: Higher positive charges on the metal ion attract ligands more closely, increasing orbital repulsion and Ξ_o (II). Step 3: Moving from 3d to 4d to 5d transition series increases orbital size and splitting energy (III). Since all three statements are correct, option (a) is correct.
