Step-by-step solution

For W: [ Co ( NH ₃)₅ Cl ] Cl ₂ : Co is in +3 oxidation state. Co³⁺ is d^6 . With strong field ligands like NH ₃ , it forms a low spin complex with = 0 BM. This corresponds to R. For X: K ₄ [ Mn ( CN )₆ ] . Mn is in +2 oxidation state. Mn²⁺ is d^5 . CN ⁻ is a strong field ligand, causing pairing, resulting in one unpaired electron ( t_ 2g ^5 e_g^0 ). = 1(1+2) = 1.732 BM. This corresponds to S. For Y: [ CrCl ₃( py )₃ ] . Cr is in +3 oxidation state. Cr³⁺ is d^3 . In octahedral geometry, t_ 2g ^3 e_g^0 , three unpaire
