Question

Assertion: Mohr’s salt, FeSO4·(NH₄)₂SO₄·6H₂O is not a coordination compound.

Reason: The aqueous solution of this salt gives the test of Fe²⁺, NH₄ and \[\ce{SO^{4-}_2}\] ions.

Options

• If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.

• If both Assertion and Reason are CORRECT but Reason is not the CORRECT explanation of the Assertion.

• If Assertion is CORRECT but Reason is INCORRECT.

• If Assertion is INCORRECT but Reason is CORRECT.

Answer 1

If both Assertion and Reason are CORRECT but Reason is not the CORRECT explanation of the Assertion.

Explanation:

Mohr’s salt (FeSO₄·(NH₄)₂SO₄·6H₂O) is not a coordination compound because Mohr’s salt is a double salt compound.

The solution of Mohr’s salt gives Fe²⁺, \[\ce{NH^{+}_4}\], and \[\ce{SO^{4-}_2}\]​ ions. This is also correct, but it doesn’t explain why Mohr’s salt is not a coordination compound, as coordination compounds can also dissociate into ions.
