Which of the following reaction represents Deacon's method?

  1. A \(2 \mathrm{H}_2 \mathrm{O}+2 \mathrm{Cl}_2 \stackrel{\text { Sunlight }}{\longrightarrow} 4 \mathrm{HCl}+\mathrm{O}_2\)
  2. B \(4 \mathrm{HCl}+\mathrm{O}_2 \underset{723 \mathrm{~K}}{\stackrel{\mathrm{CuCl}_2}{\longrightarrow}} 2 \mathrm{H}_2 \mathrm{O}+\mathrm{Cl}_2\)
  3. C \(2 \mathrm{NaCl}+2 \mathrm{H}_2 \mathrm{O} \stackrel{\text { Electrolysis }}{\longrightarrow} 2 \mathrm{NaOH}+\mathrm{H}_2+\mathrm{Cl}_2\)
  4. D \(\mathrm{Ca}(\mathrm{OH})_2+\mathrm{Cl}_2 \rightarrow \mathrm{CaOCl}_2 \cdot \mathrm{H}_2 \mathrm{O}\)

Answer & Solution

Correct Answer

(B) \(4 \mathrm{HCl}+\mathrm{O}_2 \underset{723 \mathrm{~K}}{\stackrel{\mathrm{CuCl}_2}{\longrightarrow}} 2 \mathrm{H}_2 \mathrm{O}+\mathrm{Cl}_2\)

Step-by-step Solution

Detailed explanation

Deacon's method involves preparation of \(\mathrm{Cl}_2\) from \(\mathrm{HCl}\) gas by oxidation, a+ about \(723 \mathrm{~K}\) in the presence of catalysts like \(\mathrm{CuCl}_2\).…
