Poorest conductor of electric current is a. sucrose, [tex] C_{12} H_{22} O_{11}[/tex](aq)
The conduction of electricity in the solution depends upon the constituents ions. The solution of ionic compounds contains the captions and anions which carry the charge making the current flow and thus conducting electricity.
Among the given option, sodium chloride dissociates into cation sodium nd anion chloride ions. Potassium nitrate dissociates into potassium ions as captions and nitrate ions as anions. Lithium hydroxide also has lithium ions as positively charged and hydroxide ions as negatively charged. Sulphuric acid releases protons and sulphate ions.
Sucrose or [tex] C_{12} H_{22} O_{11}[/tex] do not dissociate into constituent ions due to covalent bonds. Thus, they are the poorest conductors of electricity.
