Question

 

In the reactions  

   

two isomers of the product are obtained. The initial complex is

Solution

Correct option is

Cis isomer

The initial complex must have two Cl ions in cis position as the third Clion could replace an ammonia cis to both or trans to one giving two isomers. If two Cl ions were in the trans positions, the other four oppositions which could be replaced are equivalent and only one isomer of the product would be obtained.
