Given below are two statements.

Statement I: In , Cu-O bonds are present.

Statement II: In , ligands coordinating with Cu(II) ion are O- and S-based ligands.

In the light of the above statements, choose the correct answer from the options given below
  1. (A)Both Statement I and Statement II are correct
  2. (B)Both Statement I and Statement II are incorrect
  3. (C)Statement I is correct but Statement II is incorrect✓ Correct
  4. (D)Statement I is incorrect but Statement II is correct

Answer: (C)

Solution

Statement I is correct: in , copper forms coordinate bonds with oxygen atoms from water molecules. Statement II is incorrect: the ligands coordinating with Cu(II) are only oxygen-based (from water molecules); sulfur from the sulfate ion does not coordinate directly with copper. The structure is .
