Question

Select wrong chemical reaction among thefollowing:, $ \mathrm{MnO}_{2}+4 \mathrm{HCl} \rightarrow \mathrm{MnCl}_{2}+\mathrm{Cl}_{2}+2 \mathrm{H}_{2} \mathrm{O} $, $ 8 \mathrm{NH}_{3}+3 \mathrm{Cl}_{2} \rightarrow 6 \mathrm{NH}_{4} \mathrm{Cl}+\mathrm{N}_{2} $, $ 2 \mathrm{NaOH}+\mathrm{Cl}_{2} \rightarrow 2 \mathrm{NaCl}+\mathrm{H}_{2}+\mathrm{O}_{2} $, $ 2 \mathrm{Ca}(O H)_{2}+2 \mathrm{Cl}_{2} \rightarrow \mathrm{Ca}(O C l)_{2}+\mathrm{CaCl}_{2}+2 \mathrm{H}_{2} O $

MARKS App · Accepted Answer

When $ \mathrm{NaOH} $ reacts with $ \mathrm{Cl}_{2} $, hydrogen gas does not liberate, therefore, this reaction is wrong reaction. Correct reaction is, $ 2 \mathrm{NaOH}+\mathrm{Cl}_{2} \rightarrow \mathrm{NaCl}+\mathrm{NaClO}+\mathrm{H}_{2} \mathrm{O} $
