The EAN of metal atoms in $[Fe {(CO)}_{2} {(NO}^{+})_{2}]$ is 'x' and EAN of metal atoms in ${Co}_{2} {(CO)}_{8}$ is 'y'. The value of $x + y$ is

Answer:

72.00

Solution:

Oxidation state of iron in $[Fe {(CO)}_{2} {({NO}^{+})}_{2}] = x + 2 (0) + 2 = 0; x = - 2$
So, EAN $= 26 - (- 2) + 8 = 36 = x$

Oxidation state of cobalt in $C o_{2} {(CO)}_{8} = 2 x + 8 (- 0) =$ or $x = 0$
So, EAN $= 27 + 1 + 8 = 36 = y$
So, $x + y = 72$
