Comprehension Type
Direction (Q. Nos. 16 and 17) This section contains a paragraph, each describing theory, experiments, data, etc. Two questions related to the paragraph have been given. Each question has only one correct answer among the four given options (a), (b), (c) and (d).
Passage
A metal complex having the composition Cr(NH3)4CI2Br has been isolated in two forms A and B. The form A reacts with AgNO3 to give a white precipitate readily soluble in dilute aqueous ammonia whereas B gives a pale yellow precipitate soluble in cone, ammonia.
Q.

- a)[Cr(NH3)4Br]CI2
- b)[Cr(NH3)4CIBr]CI
- c)[Cr(NH3)4CI2]Br
- d)Both (a) and (b)
Correct answer is option 'B'. Can you explain this answer?

Comprehension Type Direction (Q. Nos. 16and 17) This section contains ...
Explanation:
To determine the formula of complex A, we need to analyze the given information. Let's break down the information provided in the paragraph:
1. The metal complex has the composition Cr(NH3)4CI2Br, indicating it contains a central chromium atom (Cr) coordinated with 4 ammonia molecules (NH3), 2 chloride ions (CI-), and 1 bromide ion (Br-).
2. The complex exists in two forms, A and B.
3. When form A reacts with AgNO3 (silver nitrate), it gives a white precipitate that is readily soluble in dilute aqueous ammonia. This indicates that the precipitate formed is silver chloride (AgCI), which is soluble in dilute ammonia.
4. When form B reacts with AgNO3, it gives a pale yellow precipitate that is soluble in concentrated ammonia. This indicates that the precipitate formed is silver bromide (AgBr), which is soluble in concentrated ammonia.
Based on this information, we can determine the formula of complex A:
- The white precipitate formed when A reacts with AgNO3 is AgCI, indicating that CI- is present in form A.
- The pale yellow precipitate formed when B reacts with AgNO3 is AgBr, indicating that Br- is present in form B.
Therefore, the formula of complex A should contain CI2 and not Br. Among the given options, only option (b) [Cr(NH3)4CIBr]CI satisfies this condition. The formula of complex A is [Cr(NH3)4CI2]Br.
Answer: The formula of complex A is [Cr(NH3)4CI2]Br.

Therefore, the formula of complex A should contain CI2 and not Br. Among the given options, only option (b) [Cr(NH3)4CIBr]CI satisfies this condition. The formula of complex A is [Cr(NH3)4CI2]Br.
Answer: The formula of complex A is [Cr(NH3)4CI2]Br.
