JEE Mains · Chemistry · STD 11 - 8.3. Organic chemistry purification and characterization
In Carius method of estimation of halogen, 0.25 g of an organic compound gave 0.15 g of silver bromide \((\mathrm{AgBr})\). The percentage of Bromine in the organic compound is _______ \(\times 10^{-1 \%}\) (Nearest integer).
(Given : Molar mass of Ag is 108 and Br is \(80 \mathrm{~g} \mathrm{~mol}^{-1}\) )
- A 250
- B 255
- C 260
- D 665
Answer & Solution
Correct Answer
(B) 255
Step-by-step Solution
Detailed explanation
Mass of organic compound \(=0.25 \mathrm{~g}\) Mass of \(\mathrm{AgBr}=0.15 \mathrm{~g}\) No. of moles of \(\mathrm{Br}=\) No. of moles of \(\mathrm{AgBr}=\frac{0.15}{188}\)…
