NEETChemistryCoordination Compounds
Given below are two statements : Statement I: Ni CN 4 2 - is square planar and diamagnetic complex, with dsp 2 hybridization for Ni but Ni CO 4 is tetrahedral, paramagnetic and with sp 3 hybridication for Ni . Statement II : NiCl 4 2 - and Ni CO 4 both have same d-electron configuration, have same geometry and are paramagnetic. In light the above statements, choose the correct answer form the options given below
Options
- ABoth Statement I and Statement II are true.
- BStatement I is correct but statement II is false.
- CStatement I is incorrect but statement II is true.
- DBoth Statement I and Statement II are false.
Correct answer
D. Both Statement I and Statement II are false.
Step-by-step solution
Ni CN 4 2 - : d 8 configuration, SFL, sq. planar splitting dsp 2 , diamagnetic. Ni CO 4 : d 10 config (after excitation), SFL, tetrahedral splitting sp 3 , diamagnetic. NiCl 4 2 - : d 8 config, WFL, tetrahedral splitting sp 3 , paramagnetic( 2 unpaired e - ). Electronic configuration of Ni atom in Ni CO 4
