$ {{[Co{{(NH _3)}_4}Br _2]}^{+}}+B{r^{-}}\to [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 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:
A) (III) and (IV)
B) (II) and (IV)
C) (I) and (II)
D) (I) and (III)
Show Answer
Answer:
Correct Answer: D
Solution:
From the given 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.
Statement (I) and (III) are correct.
