Question:

In the following reactions, products (A) and (B), respectively, are:

$\mathrm{NaOH}+\mathrm{Cl}_{2} \rightarrow(\mathrm{A})+$ side products (hot and conc.)

$\mathrm{Ca}(\mathrm{OH})_{2}+\mathrm{Cl}_{2} \rightarrow(\mathrm{B})+$ side products (dry)

  1. $\mathrm{NaClO}_{3}$, and $\mathrm{Ca}(\mathrm{OCl})_{2}$

  2. $\mathrm{NaClO}_{3}$ and $\mathrm{Ca}\left(\mathrm{ClO}_{3}\right)_{2}$

  3. $\mathrm{NaOCl}$ and $\mathrm{Ca}(\mathrm{OCl})_{2}$

  4.  $\mathrm{NaOCl}$ and $\mathrm{Ca}\left(\mathrm{ClO}_{3}\right)_{2}$

Correct Option: 1

Solution:

$6 \mathrm{NaOH}+3 \mathrm{Cl}_{2} \rightarrow 5 \mathrm{NaCl}+\mathrm{NaClO}_{3}+3 \mathrm{H}_{2} \mathrm{O}$

$2 \mathrm{Ca}(\mathrm{OH})_{2}+\mathrm{Cl}_{2} \rightarrow \mathrm{Ca}(\mathrm{OCl})_{2}+\mathrm{CaCl}_{2}+\mathrm{H}_{2} \mathrm{O}$
