the sum of coordination no. and oxidation no. of the metal M in the complex [M(en)2(c2o4)]cl
where en is ethylenediamines
1)7          2)8             3) 9                  4)6       

Dear Student,

Coordination number of M = 6 as en and C2O4 both are bidentate ligands.oxidation number of M can be calculated as, x+ 2(0)+(-2)=+1or, x=+3Therefore, sum of coordination number and oxidation number= 6+3=9the correct answer is (3)
