Question

Statement-1: [Ni(CN)₆]^4- is square planar d²sp³ and diamagnetic, whereas Ni(CO)₄ is square planar and sp³ Hybridised and paramagnetic.

Statement-2: NiC₄^2- and NiCO₄ has the same d configuration, geometry and hybridization.

(a) Statement 1 and statement 2 both are correct.

(b) Statement I is correct but statement 2 is wrong.

(c) Statement 1 is wrong but statement 2 is correct.

(d) Statement 1 and statement 2 both are wrong.

Answer 1

(d) Statement 1 and statement 2 both are wrong.

 [Ni(CN)₆]^4- is paramagnetic and sp³d², octahedral 

Ni(CO)₄ is tetrahedral, dsp² hybridized and diamagnetic 

NICI₄^2- is square planar, sp³ hybridised and paramagnetic

Therefore, both the statements 1 and 2 are false
