Question

is wrong stalement but reason is correct statement.
(1) Assertion (A) : (Co(NH2),Cijso, does not give white precipitates with silver nitrate.
Reason (R): Chlorine is not present outside the coordination sphere.
(ii) Assertion (A): In K [Fe(CN),), the coordination number of iron is 6.
Reason (R) : Six CN ligands are attached to the central metal ion in the coordinate compound.
OR
Assertion (A): The oxidation number of Ni in [Ni(CN),12- is +2.
Reason (R): The charge on cyanide ion is -1 and the total charge on the complex anion is -2.
(iii) Assertion (A): The number of halide ions in [Pt(NH;),CI;]Cl is 1.
Reason (R): There are four halide ions.
(iv) Assertion A : [Fe(H20),NO]SO, is paramagnetic
Reason R : The Fe in (Fe(H20),NO]SO, has three unpaired electrons.​

Answer 1

Explanation:

Answer

Correct option is

B

Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

The [CoCl3(NH 3 ) 3] complex contains elements of symmetry and is optically inactive.

It does not give white precipitate with silver nitrate solution as chlorine is present in the coordination sphere.

Thus Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
