A Coordination compound is represented by the formula \([\mathrm{CoBr}_3(e n) x]\). This compound required one mole of \(\mathrm{AgNO}_3\) to form a pale yellow precipitate of \(\mathrm{AgBr}\). What is the value of \(\mathrm{x}\) in the compound?
- A 4
- B 1
- C 2
- D 3
Answer & Solution
Correct Answer
(C) 2
Step-by-step Solution
Detailed explanation
The coordination compound is given as \([CoBr_3(en)x]\). The reaction with \(AgNO_3\) produces a pale yellow precipitate of \(AgBr\), which indicates that one bromide ion is present outside the coordination sphere as a counter ion. The reaction can be represented as…
