High boiling point and low melting point. H2Se gas is used to dope semiconductors with selenium. Water molecules experience hydrogen bonds whereas hydrogen sulfide (H2S) molecules experience dipole forces. In H2O and H2S , Oxygen and Sulphur are the central atoms respectively.Among Oxygen and Sulphur , Oxygen is more electronegative (tendency to gain electrons) and hence it can form more number of intermolecular H bonding with other water molecules than Sulphur in H2S. The gas can be detected at a level of 2 parts per billion. Therefore, $ {H_2}O $ will have the highest boiling point among the given compounds. Since S, Se, Te are in the same group of the periodic table - so they have the same type of forces/bonding. Liquids have much higher densities in comparison to gases. In this case, look at the molecular weight. This in turn will increase the energy needed to pull the molecules apart, thus an increase in the boiling point .

The selenide, in contrast, forms Hydrogen sulfide provides sulphur source to copper indium gallium film to adjust the light absorption bandgap in chalcogenide thin film photovoltaics. Water is more polar than hydrogen sulfide because the oxygen atom is more electronegative than the sulfur atom. H2S < H2Se < H2Te < H2O This is the correct boiling point order. Why is the boiling point of hydrogen always higher? It does not store any personal data. [5] Exposure at high concentrations, even for less than a minute, causes the gas to attack the eyes and mucous membranes; this causes cold-like symptoms for at least a few days afterwards. This essentially means H2Se is a bigger molecule than H2S meaning the Van Der Waal forces (London forces) on H2Se is stronger than on H2S which means it takes more energy to break the intermolecular forces for H2Se than H2S- this leads to H2S having the lower boiling point. 5 Why does H2S has lower boiling point than H2Se? vaporized on boiling consisting on average of several water The threshold limit value is 0.05 ppm.
