One mole of an octahedral metal complex with the formula MCl3·2L reacts with an excess of AgNO3 solution to precipitate exactly 1 mole of AgCl. What is the denticity of the neutral ligand L?

Consider the following statements based on Crystal Field Theory (CFT): Statement I: An electron in eg orbitals causes destabilization by 0.6 Δo and an electron in t2g orbitals causes stabilization by 0.4 Δo. Statement II: All d-orbitals of transition metal ions are degenerate in the absence of surrounding ligands, but splitting occurs in an octahedral ligand field. Choose the correct option:

Match Column-I (Complex) with Column-II (Spin-only magnetic moment in BM): Column-I: (A) [Cr(H2O)6]3+ (B) [Cu(H2O)6]2+ (C) [Mn(H2O)6]2+ (D) [Co(H2O)6]3+ Column-II: (P) 1.73 (Q) 3.87 (R) 0 (S) 5.93
