A) 6, 4
B) 4, 6
C) 5, 8
D) 8, 5
Correct Answer: B
Solution :
EAN = Z (atomic number of the metal) - number of electrons lost in the ion formation + number of electrons gained from the donor atoms of the ligands. \[EAN=28-0+2x=36\] \[2x=36-28\] \[2x=8\] \[x=4\] The formula of the compound is\[Ni\,{{(CO)}_{4}}\]. \[{{K}_{4}}[Fe{{(CN)}_{x}}]\] \[EAN=(26-2)+(2x)=36\,(Kr)\] \[x=6\] \[\therefore \]The formula of the compound is \[{{K}_{4}}[Fe{{(CN)}_{6}}].\]You need to login to perform this action.
