Assertion: [Ni(en)₃Cl₂]Cl₂ (en = ethylene diamine) has lower stability than [Ni(NH₃)₆Cl₂].
Reason: In [Ni(en)₃Cl₂], the geometry of Ni is trigonal bipyramidal.

A
(a)

B
(b)

C
(c)

D
(d)

Solution

Stability is more in case of chelating ligands. In [Ni(en)₃]Cl₂, thegeometry of nickel is octahedral.
Question 4
1 / -0

Which of the following complexes is/are of low spin?

A
[Co(H₂O)₆]³⁺

B
[Ni(CN)₄]^2-

C
[CoF₆]^3-

D
All of the above

Solution

The complex has a square planar shape.
CN^- is a strong-field ligand.
The d electron configuration of Ni²⁺ is d⁸.
The splitting energy is large.
Therefore, the complex is of low spin.

A
cobalt(II) ion

B
cobalt(III) ion

C
chromium(II) ion

D
chromium(III) ion
