The co-ordination number and the oxidation state of the element ' ( M ) ' in the complex ( [ M ( en )₂ ( C ₂ O ₄ ) ] NO ₂ ) [where (en) is ethan-1,2 - diamine] are respectively

Options

  1. A( 6 ) and ( 3 )
  2. B( 6 ) and ( 2 )
  3. C( 4 ) and ( 2 )
  4. D( 4 ) and ( 3 )

Correct answer

A. ( 6 ) and ( 3 )

Step-by-step solution

Oxidation number of ( M ) metal ion in the given complex, ( x+(2 0)+1 (-2)=1 ) ( x=+3 ) Since, metal is linked with ( 6 ) donor sites. Therefore, coordination no. is ( 6 ) The coordination number is six and the oxidation state of theelement ( M ) in the complex ( [ M ( en )₂ ( C ₂ O ₂ ) ] N O ₂ ) is ( +3 )
