Show full solutionCorrect option: B
Correct answer
B4 and 1
Step-by-step explanation
CuSO4.5H2O [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
