Question

Consider the following reaction and statements:
$\left[Co\right(N{H}_3{)}_{4}B{r}_2{]}^{+}\to \left[Co\right(N{H}_3{)}_{3}B{r}_3]+N{H}_3$

(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 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:

• A. (II) and (IV)
• B. (I) and (II)
• C. (I) and (III)
• D. (III) and (IV)

Answer 1
