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

Correct answer

Step-by-step 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
