Answer

Explanation:

Step1: Understand electrical - conductivity principle

A solution conducts electricity if it contains ions.

Step2: Analyze each reaction

  • For $\mathrm{CH_3OH(l)}\to\mathrm{CH_3OH(aq)}$, methanol is a covalent compound and does not dissociate into ions in solution.
  • For $\mathrm{CaBr_2(s)}\to\mathrm{Ca^{2 +}(aq)}+2\mathrm{Br^-(aq)}$, calcium bromide is an ionic compound and dissociates into ions in solution, so the solution conducts electricity.
  • For $\mathrm{HF(g)}+\mathrm{H_2O(l)}\rightleftharpoons\mathrm{H_3O^{+}(aq)}+\mathrm{F^-(aq)}$, hydrogen - fluoride is a weak acid that dissociates to form ions in solution, so the solution conducts electricity.
  • For $\mathrm{NH_3(g)}+\mathrm{H_2O(l)}\rightleftharpoons\mathrm{NH_4^{+}(aq)}+\mathrm{OH^-(aq)}$, ammonia reacts with water to form ions in solution, so the solution conducts electricity.

Answer:

$\mathrm{CH_3OH(l)}\to\mathrm{CH_3OH(aq)}$
