Text Solution

Verified by Experts

(i) Given complex `[Fe(en)_(2)Cl_(2)]Cl`
` x + (0) + 2(-1) + (-1) = 0`
`implies " " x - 3 = 0`
`therefore " " x = 3`
`therefore " " ` oxidation number of Fe = 3
(ii) Hybridisation : `d^(2) sp^(3)`
Shape of complex : octahedral
(iii) Paramagnetic
(vi) Two
(v) No
(vi) Dichloridobis (ethan-1,2-diamine ) Iron (III) Chloride.
