Number of water molecules acting as ligands in
`CuSO_(4).5H_(2)O,ZnSO_(4).5H_(2)O,FeSO_(4).7H_(2)O` respectively are .

Options

A. 5,5,7
B. 4,5,4
C. 4,4,6
D. 4,4,7

Answer

C

Explanation

Coordination number of `Cu^(2+), Zn^(2+) and Fe^(2+) ` are 4,4and 6 respectively.
`i. [Cu(H_2 O)_4]SO_4* H_2 O`
`ii. [Zn (H_2 O)_4] SO_4* H_2 O`
`iii. [Fe(H_2 O)_6]SO_4* H_2 O`
