Consider the following statements ;
S1 : The [Co(ox)3]3 – complex is diamagnetic and gains stability through chelation.
S2 :The [Co(NO2)6]4 – is inner orbital complex involving d2sp3hybridisation and is paramagnetic.
S3 :The complex [PtCl4]2 – is square planar and diamagnetic. and arrange in the order of true / false
Text Solution
Verified by ExpertsA
S1 :
chelate complex, diamagnetic and has d2sp3 hybridisation.
[Co(ox)3]3 – 3d6
S2 : NO2– is strong field ligand and thus it is inner orbital complex and paramagnetic with one unpaired electron present in higher 4d-orbital
[Co(NO2)6]4– 3d7
S3 : 5d8 configuration; thus diamagnetic and dsp2 hybridisation (5d8 has higher CFSE so that Δ o > p)
