COMEDK · Chemistry · 13. General Organic Chemistry
An organic compound weighing \(0.15 \mathrm{~g}\) gave on Carius estimation, \(0.12\) gf \(\mathrm{AgBr}\).
The percentage of Br in the compound will be close to (Atomic mass of Ag \(=108, \mathrm{Br}=80\) )
- A \(46 \%\)
- B \(34.1 \%\)
- C \(3.41 \%\)
- D \(4.6 \%\)
Answer & Solution
Correct Answer
(B) \(34.1 \%\)
Step-by-step Solution
Detailed explanation
Percentage of bromine in the compound \[ \begin{aligned} &=\frac{80}{188} \times \frac{\text { Mass of } \mathrm{AgBr} \text { formed }}{\text { Mass of substance taken }} \times 100 \\ &=\frac{80}{188} \times \frac{0.12}{0.15} \times 100=34.04 \% \end{aligned} \]
