The oxygen atom polarizes electron density away from the bond to give "^(delta+)H-O^(delta-)-H . What is the boiling point of H2Se? Then figure out what the total cost of the trip would be.? So I initially thought, since S has a higher electronegativity than Se, H2S would have the higher boiling point. Which of the following has highest boiling point? h2s vs h2se boiling point H2O, 100oC; H2S, -60oC; H2Se, -41oC; H2Te, -2oC (2 marks) Generally, the boiling points in a series increases with the molecular mass and this would put the boiling point of water below -60o C. The boiling point of water is high because of the extensive H-bond between the water molecules. 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. Please helo me pick my A-levels. 3 Does H2S have the highest boiling point?

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. [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. H2Te because of higher molecular weight. H2Te has the highest molecular weight and thus it has the highest boiling point from H2S and H2Se. Consistent with this structure, three IR-active vibrational bands are observed: 2358, 2345, and 1034cm1.

Water has a higher boiling point than hydrogen sulphide. H2Se is commonly used in the synthesis of Se-containing compounds. This cookie is set by GDPR Cookie Consent plugin. And which explanation would be correct? 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.

Hydrogen sulfide occurs naturally in crude petroleum, natural gas, volcanic gases, and hot springs. A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. asked Mar 12, 2019 in Chemistry by Daisha (70.9k points) s-block . By comparing H2O with H2S, H2Se and H2Te, we can see that the boiling points will increase from H2S to H2Te because of the increasing molecular weights. In binary acids such as H2S and H2Se, the H-Se bonds is longer than the H-S bonds as Se is larger than S. The H-Se bond is therefore weaker than the H-S bond and H2Se is thus a stronger acid than H2S. These cookies track visitors across websites and collect information to provide customized ads.

As the molar mass increases boiling point of the hydrides increases except H2O. The effect of hydrogen bonding is significantly less for the other elements of the chalcogenide group. 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.
