Assertion . : The `[Ni(en)_3]Cl_3` has lower stability than `[Ni(NH_3)_6]Cl`.
Reason : In `[Ni(en)_3]Cl_2` the geometryis trigonal bipyramidal.

Options

A. If both (A) and (R) are correct and (R) is the correct explanation of (A).
B. If both (A) and (R) are correct, but (R) is not the correct explanation of (A).
C. If (A) is correct, but(R) is incorrect.
D. If both (A) and (R) are.incorrect.

Answer

D

Explanation

`[Ni(en)_2]CI_2` has greater stability than `[Ni(NH_3)_6] Cl_2 , [Ni(en)_3]Cl_2` has bidentate ligand, en, forming chelates.
