STATEMENT-1: The `[Ni(en)_(3)]Cl_(2)` has higher stability than `[Ni(NH_(3))_(6)]Cl_(2)`
and
STATEMENT-2: Ethylene diamine shows chelation with `Ni^(+2)` ion .

A

If both assertion and reason are true and reason is the explaination of assertion.

B

If both assertion and reason are true but reason is not the correct explaination of assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
`[Ni(en)_(3)]Cl_(2)` is a chelating compound and chelated complexes are more stable than similar complexes with unidentate ligands as dissociation of the complex involves breaking of two bonds rather than one.In `[Ni(en)_(3)]Cl_(2)]`,Ni with`D^(8)` configuration shows octahedral geometry.Six electrons will occuoy the`t_(2_(g))`orbitals and two electrons will occupy the `e_(g)` orbitals.
