When a stone is thrown into the water then transverse waves are formed but it is said that longitudinal waves can travel through any medium solid , liquid and gases then why a longitudinal wave does not form in water when a stone is thrown.

Longitudinal waves are formed, but the thing is that you cannot see a longitudinal wave even in water. The sound produced in water, due to the stone is a longitudinal wave only, the disturbance on the surface however is a transverse wave only.
