Answer
Distilled water consists entirely of molecules. Due to the lack of ions, it does not conduct electricity. Rain water on the other hand contains small traces of acids formed due to the dissolutions of atmospheric gases like carbon dioxide, sulphur dioxide, etc. Hence, due to the presence of ions, rain water can conduct electricity.
