  2. B \(\mathrm{Ca}(\mathrm{OH})_2+\mathrm{Cl}_2 \xrightarrow{\Delta} \mathrm{CaOCl}_2+\mathrm{H}_2 \mathrm{O}\)
  3. C \(\mathrm{Ba}(\mathrm{OH})_2+\mathrm{Br}_2 \xrightarrow{\Delta} \mathrm{BaOBr}_2+\mathrm{H}_2 \mathrm{O}\)
  4. D \(\mathrm{Ca}(\mathrm{OH})_2+\mathrm{F}_2 \xrightarrow{\Delta} \mathrm{CaOF}_2+\mathrm{H}_2 \mathrm{O}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(\mathrm{Ca}(\mathrm{OH})_2+\mathrm{Cl}_2 \xrightarrow{\Delta} \mathrm{CaOCl}_2+\mathrm{H}_2 \mathrm{O}\)

Step-by-step Solution

Detailed explanation

The chemical formula of bleaching powder is \(\mathrm{CaOCl}_2\), so the correct reaction is \(\mathrm{Ca}(\mathrm{OH})_2+\mathrm{Cl}_2 \stackrel{\Delta}{\longrightarrow} \mathrm{CaOCl}_2+\mathrm{H}_2 \mathrm{O}\)
