The number of hydrogen bonded water molecule(s) associated with CuSO ₄ 5 H ₂ O is

Options

  1. A3
  2. B1
  3. C2
  4. 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 .
