हैलोजन आकलन की कैरिअस विधि में एक कार्बनिक यौगिक के \(0.45 g\) से \(0.36 g AgBr\) प्राप्त होता है। यौगिक में ब्रोमीन का प्रतिशत ज्ञात \(......../%\) कीजिए। (मोलर द्रव्यमान: \(AgBr =188\,g\,mol ^{-1}\).\(Br =80\,g\,mol ^{-1}\) है।)

  1. A \(34.04 \%\)
  2. B \(40.04 \%\)
  3. C \(36.03 \%\)
  4. D \(38.04 \%\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(34.04 \%\)

Step-by-step Solution

Detailed explanation

Mass of organic compound \(=0.45\,gm\) Mass of \(AgBr\) obtained \(=0.36\,gm\) \(\therefore\) Moles of \(AgBr =\frac{0.36}{188}\) \(\therefore\) Mass of Bromine \(=\frac{0.36}{188} \times 80=0.1532\,gm\) \(\therefore \% Br\) in compound…
