In water molecules the more electronegative oxygen atoms has small size and is present as a central atom, so that it form intermolecular hydrogen bonding strongly. But in case of H2s molecule, the central atom Sulphur is less electronegative and is bigger in size, so that it is unable to form the intermolecular hydrogen bonding. Therefore, H2s doesn't exist in liquid state. Hope this helps... Darshana?
