The co-ordination number and the oxidation state of the element .M. in the complex `[M(en)_2(C_2O_4)] NO_2` {where (en) is ethan-1, 2-diamine} are respectively

A

6 and 2

B

4 and 2

C

6 and 3

D

4 and 3

Text Solution

Verified by Experts

The correct Answer is:
C
Let the oxidation state of metal ' M' be x.
For complex, `[M (en)_(2)(C_(2)O_(4))] NO_(2)`
X + 0 -2 = +1
x = +3
