Question

2.
The coordination number and oxidation number of
the central metal ion in the complex (Pt(en)2)+2 is :-
(1) C.N. = 2, O.N. = +2
(2) C.N. = 6, Q.N. = +4
(3) C.N. = 4, Q.N. = +4
(4) C.N. = 4, Q.N. = +2

Answer 1

Answer:

4

Explanation:

En is ethane 1-2,diamine so bidentate l i g a n d , there's two of them so the coordination number should be 4 , it's a neutral l i g a n d so the overall charge on the coordination sphere should be because of the oxidation state of platinum which is plus two
