On the other hand, H2Se and H2Te contain hydrogens that are not attached to electronegative elements, so they cannot undergo hydrogen bonding, and they possess boiling points that are significantly lower than water. This cookie is set by GDPR Cookie Consent plugin. 212F (100C) H2S is more polar than H2Se because H2S has greater dipole-dipole forces than H2Se since the H-S bond is more polar than the H-Se bond. We don't collect information from our users. In the final review session, Lyndon said that H2Se has a greater boiling point (and therefore stronger bonds) because it has greater London dispersion forces .

This is because of the lower electronegativity of sulphur than oxygen. Copyright The Student Room 2023 all rights reserved. If true enter 1 else 0. The intermolecular attractions between water molecules are stronger than H2S molecules due to hydrogen bonding in H2O due to high electronegativity and small size of oxygen atom.

H2Se is commonly used in the synthesis of Se-containing compounds. In the final review session, Lyndon said that H2Se has a greater boiling point (and therefore stronger bonds) because it has greater London dispersion forces than H2S does. [8] A number of routes to H2Se have been reported, which are suitable for both large and small scale preparations. Knowing that hydrogen bonds are stronger than dipole-dipole forces, this leads to : water has a higher boiling point than hydrogen sulfide because hydrogen bonds are much stronger than dipole-dipole bonds. 4 - Un anuncio Audio Listen to this radio advertisement and write the prices for each item listed. Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water. Hydrogen sulfide - Thermophysical Properties, STP - Standard Temperature and Pressure & NTP - Normal Temperature and Pressure, Heat (enthalpy) of sublimation,at -145F/-98C, Specific heat capacity, Cp (liquid) at 20 bara, Specific heat capacity, Cv (liquid) at 20 bara, Specific Gravity (liquid) (relativ to water), Specific Heat Ratio (liquid) - CP/CV at 20 bara, Specific Volume (liquid) at -121.9 F/-85.5C. -86.31F (-65.73C) Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. Fher, F. In "Handbook of Preparative Inorganic Chemistry"; Brauer, E., Ed. For example, water boils at 100 C (212 F) at sea level, but at 93.4 C (200.1 F) at 1,905 metres (6,250 ft) altitude.

However, in the chemistry textbook version 6 p.484, H2Se is expected to be a stronger acid than H2S because H2Se has weaker bonds. >. [6], The properties of H2S and H2Se are similar, although the selenide is more acidic with pKa = 3.89 and the second pKa = 11,[6] or 15.05 0.02 at 25C.

Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water. Hydrogen sulfide is a colorless gas with an offensive stench and is said to smell like rotten eggs. In binary acids such as H2S and H2Se, the HSe bonds is longer than the HS bonds as Se is larger than S. The HSe bond is therefore weaker than the HS bond and H2Se is thus a stronger acid than H2S.

Begin typing your search term above and press enter to search. 3. As the molar mass increases boiling point of the hydrides increases except H2O. Thus, there will always be some degree of induced dipole-induced dipole (also known as LDF). > H2S < H2Se < H2Te < H2O Thi O This is the correct boiling point order. In the final review session, Lyndon said that H2Se has a greater boiling point (and therefore stronger bonds) because it has greater London dispersion forces than H2S does. H2Se has the higher boiling point because it has a larger mass and more electrons. The intermolecular attractions between water molecules are stronger than H2S molecules due to hydrogen bonding in H2O due to high electronegativity and small size of oxygen atom. Thus, the boiling point of H2S is lower than that of H2O. The cookies is used to store the user consent for the cookies in the category "Necessary".
