Consider the following reaction and statements :

[Co(NH_{3})_{4}Br_{2}]^{+}+Br^{-}[Co(NH_{3})_{3}Br_{3}]+NH_{3}

(I) Two isomers are produced if the
     reactant complex ion is a cis-isomer.

(II) Two isomers are produced if the
     reactant complex ion is a transisomer.

(III) Only one isomer is produced if the
       reactant complex ion is a transisomer

(IV) Only one isomer is produced if the
        reactant complex ion is a cis-isomer.

The correct statements are :

  • Option 1)

    (II) and (IV)

  • Option 2)

    (I) and (II)

  • Option 3)

As we learned

Optical Isomerism -

Optical isomers are mirror images that cannot be suprimposed on one another

-

 

 \left [ Ma_{4}b_{2} \right ]+b\rightarrow \left [ Ma_{3}b_{3} \right ]+a

 

Two possibilities for \left [ Ma_{4}b_{2} \right ]

 


Option 1)

(II) and (IV)

Option 2)

(I) and (II)

Option 3)

(I) and (III)

Option 4)

(III) and (IV)
