Given below are two statements.

Statement I: In

CuSO X_{4} \cdot 5 H X_{2} O

, Cu-O bonds are present.

Statement II: In

CuSO X_{4} \cdot 5 H X_{2} O

, 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

(A)Both Statement I and Statement II are correct
(B)Both Statement I and Statement II are incorrect
(C)Statement I is correct but Statement II is incorrect✓ Correct
(D)Statement I is incorrect but Statement II is correct

Answer: (C)

Solution

Statement I is correct: in

CuSO X_{4} \cdot 5 H X_{2} O

, 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

[Cu (H X_{2} O) X_{4}] SO X_{4} \cdot H X_{2} O
