Consider the following reaction and statements:

CoNH34Br2++Br-CoNH33Br3+NH3

(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 trans-isomer.

(iii) Only one isomer is produced if the reactant complex ion is a trans-isomer.

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

The correct statements are

Options:

Answer:
C
Solution:

From the below image it is clear that two isomers are produced if the reactant complexion is a cis-isomer, as well as only one isomer, is produced if the reactant complex is a trans-isomer.

Two isomers are produced if the reactant complex ion is a cis-isomer because the cis isomer can further form facial and meridional isomers.

Only one isomer is produced if the reactant complex ion is a trans-isomer because it cannot form any isomeric isomers.

Trans → only meridonial

Cis → fac and mer
