NEET2019ChemistryChemical Bonding and Molecular StructureActual
The number of hydrogen bonded water molecule(s) associated with CuSO ₄ 5 H ₂ O is
Options
- A3
- B1
- C2
- D5
Correct answer
B. 1
Step-by-step solution
Cu ²⁺ ion has 17 electrons in its outermost orbital. 4 H ₂ O molecules donate 4 pairs of electrons for coordinate covalent sharing. The one H ₂ O molecule is attached to the sulphate ion by hydrogen bonding, the oxygen being oriented to the hydrated cupirc ion. Thus, the number of hydrogen bonded water molecule associated with CuSO ₄ 5 H ₂ O is 1 .
