Question

The question consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses:
Assertion: The `[Ni(en)_3]Cl_2` has higher stability than `[Ni(NH_3)_6]Cl_2`
Reason: In `[Ni(en)_3]Cl_2`, the geometry around `Ni` is octahedral.
A. (a) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. (b) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. (c) If assertion is true but reason is false.
D. (d) If assertion is false but reason is true.

Answer 1

Correct Answer - B
Assertion: The chelate complexes are more stable than similar complexes containing unidentate ligands.

Reason: `Ni^(2+)` with coordination number six forms octahedral complexes.
