Which of the following is not a disproportionation reaction?

${\text{P}}_{\text{4}}{\text{+3NaOH+3H}}_{\text{2}}\text{O}\stackrel{\Delta }{\to }{\text{PH}}_{\text{3}}{\text{+3NaH}}_{\text{2}}{\text{PO}}_{\text{2}}$

$3C{\mathcal{l}}_2+6NaOH\to 5NaC\mathcal{l}+NaCl{O}_3+3H_{2}O$

${\text{2 F}}_{\text{2}}\text{(g) + 2KOH(aq) }\stackrel{ }{\to }{\text{ 2 KF(aq) + OF}}_{\text{2}}{\text{(g) + H}}_{\text{2}}\text{O(}\mathcal{l}\text{)}$

${{\text{3MnO}}_{\text{4}}}^{\text{2-}}{\text{ + 4H}}^{\text{+}}\stackrel{ }{\to }{{\text{2MnO}}_{\text{4}}}^{\text{-}}{\text{ + MnO}}_{\text{2}}{\text{ + 2H}}_{\text{2}}\text{O}$
