Write the balanced chemical equation for the reaction of `CI_2` with hot and concentrated NaOH. Is this reactiona disporpetination reaction? Justify.

Explanation

Reaction `Cl_2` with hot and conc. NaOH

It is a disproportionation reaction as O.S. of chlorine changes from 0 in (in `Cl_2`) to -1 in NaCl) and + 5 (in `NaClO_3`).
Reaction of `Cl_2` with cold and dil. NaOH

It is a disproportionation reaction as O.S. of chlorine changes from 0 in (in `Cl_2`) to -1 (in NaCl) and +1 (in NaClO).
