Note: We should remember that volatility is inversely proportional to the boiling point of the liquid. However, at low temperature and/or high pressures the gas becomes a liquid or a solid. Why does H2S have a lower boiling point than water? The strength of LDFs depends on polarizability. Press ESC to cancel. Hydrogen sulfide/Boiling point. 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. 15%, H2Sebecause of lower molecular weight. It is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent. -42.25F (-41.25C) So, less energy is required to break the hydrogen bonds in H2S. But opting out of some of these cookies may affect your browsing experience. So despite its small molecular weight, water has an incredibly . As for these conflicting explanations, stronger bonds make boiling point greater and conversely, pH higher (less acidic).

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 . Therefore, $ {H_2}O $ will have the highest boiling point among the given compounds. LDS forces do contribute to a higher boiling point and therefore a stronger molecule. Hydrogen selenide is hazardous, being the most toxic selenium compound[3] and far more toxic than its congener hydrogen sulfide. 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. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. What is the melting point of hydrogen sulfide? If you repeat this exercise with the compounds of the elements in groups 15, 16, and 17 with hydrogen, something odd happens. Sulfur is not from these elements, therefore the dipole-dipole force between 2H2S is not a hydrogen bond. This may be a dumb question, but I was wondering about this question from Matthew Nguyen's UA Worksheets? The boiling point of hydrogen compounds of group 16 is into the order of H2O > H2S . ), How to make a New Post (submit a question) and use Equation Editor (click for details), How to Subscribe to a Forum, Subscribe to a Topic, and Bookmark a Topic (click for details), Multimedia Attachments (click for details), Accuracy, Precision, Mole, Other Definitions, Bohr Frequency Condition, H-Atom , Atomic Spectroscopy, Heisenberg Indeterminacy (Uncertainty) Equation, Wave Functions and s-, p-, d-, f- Orbitals, Electron Configurations for Multi-Electron Atoms, Polarisability of Anions, The Polarizing Power of Cations, Interionic and Intermolecular Forces (Ion-Ion, Ion-Dipole, Dipole-Dipole, Dipole-Induced Dipole, Dispersion/Induced Dipole-Induced Dipole/London Forces, Hydrogen Bonding), *Liquid Structure (Viscosity, Surface Tension, Liquid Crystals, Ionic Liquids), *Molecular Orbital Theory (Bond Order, Diamagnetism, Paramagnetism), Coordination Compounds and their Biological Importance, Shape, Structure, Coordination Number, Ligands, *Molecular Orbital Theory Applied To Transition Metals, Properties & Structures of Inorganic & Organic Bases, Acidity & Basicity Constants and The Conjugate Seesaw, Calculating pH or pOH for Strong & Weak Acids & Bases, Chem 14A Uploaded Files (Worksheets, etc. Why does water have a higher boiling point than hydrogen selenide?
