. The number of hydrogen bonded water molecule(s) associated with CuSO4.5H20 is
(a) 3
(b) 1
(c) 2
(d) 5
Best Answer
Correct Option is (b)
Cu is coordinated with four water molecules and two more oxygen atoms from the sulphate ion in CuSO4.5H2 O.
A hydrogen-bonded fifth water molecule is now deeply entrenched in a crystal. It's not coordinated.
Only four water molecules are coordinated, with the fifth being the only hydrogen-bonded water molecule.
