Which of the following statements are incorrect ? (1) `Co^(+3)` with strong field ligand forms high magnetic moment complex. (2) For `Co^(+3)` if pairing `"energy"(P) gt Delta_o` then the complex formed will have `(t_(2g)^(4),(e_g)^2)` configuration. ltbr. (3) For `[Co(en)^3]^( 3+) lambda_("absorbed")` is less than `lambda_("absorbed")` for `[CoF_6]^( 3–)` (4) If `Delta_o = 18000 cm^(–1)` for `Co^(+3)` then with same ligands for it `Delta_t = 16000 cm^(–1)`
In both the complexes Co cation have t_(2g)^6 e_g^0 configuration. The B. E. of (O–O) in X & Y is
Which of the following is more stable complex and why? [CO(NH_3)_6]^(3+) and [CO(en)_3]^(3+)
Which of the following complexes is more stable and why ? [Co(en)_3]^(3+) and [Co(NH_3)_6]^(3+)
In [(H_(2)O)_(4)Co-(O-O)-Co (H_(2)O)_(4)] CL_(5) complex, Co has t_(2g)^(6)e_(g^(0)) configuration, this complex is :
In the give complexes (i). [Co(NH_(3))_(5)(H_(2)O)]^(3+) (ii). [Co(NH_(3))_(5)Cl]^(2+) (iii). [Co(NH_(3))_(6)]^(3+) The decreasing order of lamda absorbed is
