Correct Answer: option (3) organic acids
Reason:
Electrolytes are the solutions that conduct electricity. In present case, when organic acids are dissolved in water, they generate hydrogen ions (H+). Due to the presence of free ions in solution, it conducts electricity. On other hand, compound like alcohols, alkynes and saturated hydrocarbons, when dissolved in water, do not undergo electrolysis. Hence, there are not considered as electrolytes.
