The reactions given below, \[ \begin{array}{l} \text{A } \mathrm{Cl_2} + \mathrm{H_2O} \rightarrow \mathrm{HOCl} + \mathrm{H_3O^+} + \mathrm{Cl^-} \\ \text{B } \mathrm{Cl_2} + 2\mathrm{NH_3} \rightarrow \mathrm{NH_2Cl} + \mathrm{NH_4} + \mathrm{Cl^-} \end{array} \]
are examples of (a) disproportionation only
(b) disproportionation (A) and solvation (B)
(c) solvation (A) and disproportionation (B)
(d) solvalysis as well as disproportionation
Answer Answer: D ✓ checked by 4AB · confidence high
Explanation In both reactions Cl₂ (oxidation state 0) becomes +1 (HOCl or NH₂Cl) and −1 (Cl⁻): disproportionation. The solvent (water or ammonia) is also split by the reagent: hydrolysis in (A) and ammonolysis in (B), i.e. solvolysis. Both are examples of solvolysis as well as disproportionation.
