Which compound will conduct electricity when it is dissolved in water? ch4 cuso4 c6h6 c6h12o6

I would say CuSO4 or Copper Sulfate, as option 1 is Methane and would create a fire so heat, and the last one is Sugar which doesn't conduct electricity.  And C6H6 I believe is not soluble in water.

Only CuSO4 conducts electricity in water because it is an ionic compound. The conduction of electricity is due to the ions in the ionic compound. When copper sulphate is dissolved in water, the ions dissociate and conduct electricity.
The others are do not liberate electricity when dissolved in water because ions are not liberated when electricity is passed through their solutions.

False because saturated fatty acids contain only single bond
