The coordination number and the oxidation state of the element 'E' in the complex `[E(en)_2(C_2O_4)]NO_2` (where `(en)` is ethylenediamine) are, respectively

A

4 and 3

B

6 and 3

C

6 and 2

D

4 and 2

Text Solution

Verified by Experts

The correct Answer is:
B
en and `C_(2)O_(4)^(2-)` are bidentate ligands. Therefore, co-ordination number of E is 6. The oxidation state will be `x+2(0)+2(-2)=-1or x = +3`
