Carbon tetrachloride $(C C l_{4})$ and Aluminium trichloride $(A l C l_{3})$ both are non-polar compounds. In presence of water $C C l_{4}$ forms non-conducting liquid whereas $A l C l_{3}$ conducts current.

Solution

Carbon tetrachloride $(C C l_{4})$ is insoluble in water due to its non polar nature.
As like dissolve like, therefore it does not have free ions to conduct current.
Whereas Aluminium trichloride $(A l C l_{3})$ being hygroscopic in nature partially dissolves in water.
It can dissociates in $A l^{3 +}$ and $C l^{-}$ ions and hence conduct current.
