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)`
