Explanation:
It is known that like dissolves like which means that polar substances are able to dissolve only in polar solvents.
Whereas non-polar substances are able to dissolve only in non-polar solvents.
As all organic compounds are non-polar in nature so, they are only soluble in non-polar solvents.
On the other hand, water is a polar solvent and its dissolves substances like NaCl, [tex]MgCl_{2}[/tex] etc that are also polar in nature.
Also, for a solution to conduct electricity it is necessary that there must be flow of ions from one place to another. But a non-polar or organic substance do not dissociate into ions when dissolved in water.
Hence, it is unable to conduct electricity.
Thus, we can conclude that most organic compounds are non-conducting and insoluble in water because:
- Most organic compounds don't dissolve in water because they are nonpolar.
- They don't conduct electricity because they are covalent, not ionic.
