So, in $ {H_2}O $ , there is intermolecular hydrogen bonding between the oxygen and hydrogen atoms and we know that it is one of the strongest forces. The next hydride would be H 2 O (WATER!). 7 Which of the following has lowest boiling point H2O H2S H2Se? Which one hydrogen sulphide H2S or hydrogen selenide H2Se would be expected to have the higher boiling point? This cookie is set by GDPR Cookie Consent plugin. H 2S,H 2O,H 2Se,H 2Te in order of increasing acidity. 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. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. Bigger london dispersion forces do lead to higher boiling points when a molecule exhibits no hydrogen bonds, is not polar or when the polarity is almost the same between two molecules. In this case, look at the molecular weight.

I will try to give u a most appropriate and short answer that u can understand easily See h20 has 104.5 degrees bond angle , h2s has 92degrees , h2se has 91degrees and h2te has 90degrees bond angles Draw diagrams of these u will find all of them have tetrahedral shape with 2 lone pairs , assume that no hybridization occurs and all these central . vaporized on boiling consisting on average of several water Copyright The Student Room 2023 all rights reserved. This is because of the lower electronegativity of sulphur than oxygen. Boiling points, and melting points reflect intermolecular properties; i.e. 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. Water has a higher boiling point than hydrogen selenide, because the strong hydrogen bonding of water gives it a higher effective molecular weight than hydrogen selenide, the unit that must be vaporized on boiling consisting on average of several water molecules rather than only one. Among H2S, H2Se, H2Te the strongest acid is H2Te. H2S < H2Se < H2Te < H2O This is the correct boiling point order. asked Mar 12, 2019 in Chemistry by Daisha (70.9k points) s-block .

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. -42.25F (-41.25C) Hydrogen selenide/Boiling point What is the boiling point of H2O? More the boiling point, less the volatility. Ethyl ether molecules experience only London dispersion forces whereas hydrogen sulfide (H2S) molecules experience dipole forces. Which is the most effective way to prevent viral foodborne illnesses? H2S < H2Se < H2Te < H2O This is the correct boiling point order. 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.

Which has higher boiling point H2O or H2S explain? So, less energy is required to break the hydrogen bonds in H2S. Therefore, despite the fact that HCl molecules can form stronger hydrogen bonds between themselves, the intermolecular attractions between H2S molecules still prevail as they are twice as numerous. Moving up, the next hydride would be H 2 Se (hydrogen selenide) with a boiling point of -42C.

When I was much younger, I worked in an inorganic lab whose specialty was inorganic sulfides and selenides. 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. 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 . [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. 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. 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. Why boiling point of H2O is higher than H2S and H2Se? We don't save this data. Is this a good move to take both? It can also result from bacterial breakdown of organic matter. Why does H2S have a lower boiling point than H2O and H2Se? What I dont understant is that H2S has the strongest dipole dipole interaction and since dipole-dipole interaction is stronger than dispersion force, H2S really should have higher boiling point than H2Se but why is it the opposite? It is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent. This may be a dumb question, but I was wondering about this question from Matthew Nguyen's UA Worksheets? Hydrogen sulfide, H2S, is a highly toxic and flammable, colorless gas with a characteristic odor of rotten eggs. If you want to promote your products or services in the Engineering ToolBox - please use Google Adwords. H2Se is commonly used in the synthesis of Se-containing compounds.

When looking at what has a higher boiling point, we look at what has the strongest intermolecular forces. So I initially thought, since S has a higher electronegativity than Se, H2S would have the higher boiling point. F. The (unusually) high boiling point of H2O is explained by extensive hydrogen bonding in water. -42.25F (-41.25C) So, less energy is required to break the hydrogen bonds in H2S. 1 Why is H2Se have a higher boiling point than H2S? This hydrogen chalcogenide is the simplest and most commonly encountered hydride of selenium.

Water has a higher boiling point than hydrogen selenide, because It is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent. 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. What I dont understant is that H2S has the strongest dipole dipole interaction and since dipole-dipole interaction is stronger than dispersion force, H2S really should have higher boiling point than H2Se but why is it the opposite? 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.
