Draw the structure and write the hybridisation in
(i) `[Fe(CO)_(5)]` (ii) trans`-[Co(NH_(3))_(4)Cl_(2)]^(+)` (iii) `No(CO)_(4)` (iv) `cis-[Co(NH_(3))_(4)Cl_(2)]^(+)` (v) `[NiCl_(4)]^(2-)`

Explanation

(i) `dsp^(3)` (trigonal bipyramidal) (ii) `d^(2)sp^(3)` (octahedral) (iii) `sp^(3)` (tetrahedral) (iv) `d^(2)sp^(3)` (octahedral) (v) `sp^(3)` (tetrahedral)
