JEE MAIN - Chemistry (2021 - 18th March Evening Shift - No. 7)
The secondary valency and the number of hydrogen bonded water molecule(s) in CuSO4 . 5H2O, respectively, are :
5 and 1
4 and 1
6 and 5
6 and 4
Explanation
CuSO4.5H2O $$ \Rightarrow $$ [Cu(H2O)4]SO4.H2O
In CuSO4.5H2O, Cu is co-ordinated with 4 water molecule and two more oxygen atom from sulphate ion and fifth water molecule is hydrogen bonded.
So secondary valency = 4
No. of hydrogen bond per molecule = 1
