कैरियस विधि द्वारा ब्रोमीन के एक आकलन में \(1.6 \,g\) का कार्बनिक यौगिक, \(AgBr\) का \(1.88 \,g\) देता है। यौगिक मे ब्रोमीन की संहति प्रतिशतता है ...................... (Atomic mass, \(Ag =108, Br =80 \,g mol ^{-1}\) )

  1. A \(50\)
  2. B \(55\)
  3. C \(45\)
  4. D \(40\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(50\)

Step-by-step Solution

Detailed explanation

Carius method \(\%\) of \(Br =\frac{\text { wt of } AgBr }{\text { wt. of organic compound }} \times 100 \times \frac{\text { molar mass of Br }}{\text { AgBr }}\) \(=\frac{1.88}{1.6} \times \frac{80}{188} \times 100=\frac{15040}{300.8}=50 \%\)
