[Co(NH3)5NO2]Cl2 and [Co(NH3)5(ONO)]Cl2 ...

`[Co(NH_3)_5NO_2]Cl_2` and `[Co(NH_3)_5(ONO)]Cl_2` are related to each other as

A

cis isomer

B

trans isomer

C

cis or trans isomers

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
The initial complex must have two `Cl^(-1)` ions in cis position as the third `Cl^(-1)` ion could replace an ammonia cis to both or trans to one giving two isomers. If two `Cl^(-1)` ions were in the trans position, the other four position which could be replaced are equivalent and only one isomer of the product would be obtained.
