Consider the following complex : [Cr(...

Consider the following complex `:`
`[Cr(NH_(3))_(4)(NO_(2))_(2)]:` inner orbital complex
The oxidation number, number of `d-` electrons, number of unpaired `d-` electrons on the irreleation and number of isomers are respectively.

A

`3,3,3,2`

B

`2,4,0,6`

C

`2,4,2,6`

D

`2,4,4,4`

Text Solution

Verified by Experts

The correct Answer is:
C
`._(24)Cr` is `+2` oxidation state with `[Ar]^(18)3d^(4)` configuration . It is inner orbital complex , so ,
`[overset(II)(Cr)(NH_(3))_(4)(NO_(2))_(2)]-`
Number of `d-` electrons is four and number of unpaired electrons is two.
It shows geometrical and linkage isomers.
`{:(NO_(2)-NO_(2),,cis-"trans"),(NO_(2)-ONO,,cis-"trans"),(ONO-ONO,,cis-"trans"):}`
