Co-ordination number and oxidation state of Cr in K_(3) [Cr(C_(2)O_(4)

1.	Co-ordination number and oxidation state of Cr in K_(3) [Cr(C_(2)O_(4))_(3)]are, respectively
Answer» 3 and + 3 3 and 0 6 and + 3 4 and + 2 Solution :`C_(2)O_(4)^(2-)`oxalate ion `implies` BIDENTATE ligand , So C.No = 6 `K_3[ulCr(C_2O_4)_3],+3+x+6=,x=+3`
