If there is no water on venus how lightning is occurring there?

Lightning on Venus -- as well as on any other planet -- is an important discovery because the electrical discharges drive the chemistry of an atmosphere by breaking molecules into fragments that can then join with other fragments in unexpected ways. The lightning on Venus is unique from that found on Earth, Jupiter and Saturn in that it is the only lightning known that is not ociated with water clouds. Instead, on Venus, the lightning is ociated with clouds of sulfuric acid.
