QJEEM22Ch51e4: JEE Main 2022 Chemistry - Class 12 JEEM22Ch51e4 Solution: Given below are two statements : Statement I : [Ni(CN) 4 ] 2 is …
Given below are two statements :
Statement I : [Ni(CN)4]2 is square planar and diamagnetic complex, with dsp2 hybridization for Ni but [Ni(CO)4] is tetrahedral, paramagnetic and with sp3-hybridication for Ni.
Statement II : [NiCl4]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 from the options given below :
Multiple Choice Options
- A Both Statement I and Statement II are true.
- B Both Statement I and Statement II are false.
- C Statement I is correct but Statement II is false.
- D Statement I is false but Statement II is correct.
