QJEEM22Ch4136: JEE Main 2022 Chemistry - Class 12 JEEM22Ch4136 Solution: The correct order of energy of absorption for the following…
The correct order of energy of absorption for the following metal complexes is :
A : [Ni(en)3]2+ , B : [Ni(NH3)6]2+ , C : [Ni(H2O)6]2+
Multiple Choice Options
- A C < B < A
- B B < C < A
- C C < A < B
- D A < C < B
Step-by-Step Verified Solution
Stronger is ligand attached to metal ion, greater will be the splitting between and (hence greater will be
Greater will be absorption of energy.
Hence correct order
\left[\mathrm{Ni}(\mathrm{en})_{3}\right]^{2+}>\left[\mathrm{Ni}\left(\mathrm{NH}_{3}\right)_{6}\right]^{2+}>\left[\mathrm{Ni}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{2+}
Greater will be absorption of energy.
Hence correct order
\left[\mathrm{Ni}(\mathrm{en})_{3}\right]^{2+}>\left[\mathrm{Ni}\left(\mathrm{NH}_{3}\right)_{6}\right]^{2+}>\left[\mathrm{Ni}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{2+}
