Coordination Compounds 1 Question 8
8. Consider the following reaction and statements :
$\left[Co\left(NH _3\right) _4 Br _2\right]^{+}+Br^{-} \longrightarrow\left[Co\left(NH _3\right) _3 Br _3\right]+NH _3$
I. Two isomers are produces 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
(2018 Main)
(a) (I) and (II)
(b) (I) and (III)
(c) (III) and (IV)
(d) (II) and (IV)
Show Answer
Answer:
Correct Answer: 8. (b)
Solution:
- If the reactant is cis isomer than following reaction takes place.
i.e. two isomers are produced. If the reactant is trans isomer than following reaction takes place.
i.e. only $1$ isomer is produced. Thus, statement (I) and (III) are correct resulting to option (b) as the correct answer.
