Match the complexes in Column-I with characteristic(s)/ type of hybridisation listed in column-II

Answer

(A-q,r,t); (B-q,r,t): (C-p,s): (D-q,r)

Explanation

(A) `[Co(en)_(3)]^(3+),Co^(3+) ` has `d^(6)` configuration which has higher CFSE, so hybridisation is `d^(2)sp^(3)` and complex is diamagnetic 'en' is a bidentate chelate ligand.
(B) `[Co(o x)_(3)]^(3-),Co^(3+) ` has `d^(6)` configuration which has higher CFSE, so hybridisation is `d^(2)sp^(3)` and complex is diamagnetic 'ox' is a bidentate chelate ligand.
( C) `[co(H_(2)O)_(6)]^(2+),Co^(2+)` has `d^(7)` configuration, `H_(2)O` is weak field mondentated ligand, so it is paramagnetic with three unpaired electrons having `sp^(3)d^(2)` hybridisation.
(D) ` [Co(NO_(2))_(6)]^(3-),Co^(3+)` has `d^(6)` configuration with has higher CFSE, so hybridisation is `d^(2)sp^(3)` and complex is diamagnetic . `'NO_(2)'` is a monoentate ligands.
