QJEEM20Ch2620: JEE Main 2020 Chemistry - Class 12 JEEM20Ch2620 Solution: The one that can exhibit highest paramagnetic behaviour among…
The one that can exhibit highest paramagnetic behaviour among the following is :
gly = glycinato; bpy = 2, 2'-bipyridine
gly = glycinato; bpy = 2, 2'-bipyridine
Multiple Choice Options
- A [Fe(en)(bpy)(NH3)2]2+
- B [Pd(gly)2]
- C [Co(OX)2(OH)2]– (Δ0 > P)
- D [Ti(NH3)6]3+
Step-by-Step Verified Solution
[Co(OX)2(OH)2]–
(As here 0 > P so those ligands act as strong field ligand and pairing happens.)
27Co+5 = [18Ar] 3d4 4s0( )
It has highest number of unpaired e– s. so it is most paramagnetic.
(As here
27Co+5 = [18Ar] 3d4 4s0(
It has highest number of unpaired e– s. so it is most paramagnetic.
