In the complex K4[Th(C2O4)2(H2O)2]{K}_{4} [ Th{\left({C}_{2}{O}_{4}\right)}_{2}{\left({H}_{2}O\right)}_{2} ] . If coordination number is X and oxidation number of Th is Y. The sum of X + Y is?

Correct answer

8

Step-by-step solution

K4{K}_{4}\left[Th{\left({C}_{2}{O}_{4}\right)}_{2}\left({H}_{2}O\right)\right]<br/><br/>4 + Y + 2\left(- 2\right) + 0 = 0<br/><br/>Y = + 2(oxidationnumber)<br/>Coordinationnumber(oxidation number) <br/>Coordination number( X ) = 2 \times 2 + 2 = 6<br/><br/>X + Y = 6 + 2 = 8
