Question

Assertion: \[\ce{Cr(H2O)6]Cl2 and [Fe(H2O)6]Cl2}\] are reducing in nature.

Reason: Unpaired electrons are present in their d-orbitals.

विकल्प

• Assertion and reason both are true, reason is correct explanation of assertion.

• Assertion and reason both are true but reason is not the correct explanation of assertion.

• Assertion is true, reason is false.

• Assertion is false, reason is true.

Answer 1

Assertion and reason both are true but reason is not the correct explanation of assertion.

Explanation:

In the complexes, \[\ce{Co}\] exists as \[\ce{Co^{2+}}\] and \[\ce{Fe}\] as \[\ce{Fe^{2+}}\]. Both of the complexes becomes stable by oxidation of metal ion to \[\ce{Co^{3+}}\] and \[\ce{Fe^{3+}}\].
