3. -86.31F (-65.73C) I'm not sure if the higher electronegativity of S would make the dipole-dipole interaction stronger. . Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water. The gas acts as an irritant at concentrations higher than 0.3 ppm, which is the main warning sign of exposure; below 1 ppm, this is "insufficient to prevent exposure", while at 1.5 ppm the irritation is "intolerable".

Can someone explain to me why H2Se would have the higher boiling point? A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. It is the most toxic selenium compound with an exposure limit of 0.05 ppm over an 8-hour period. Analytical cookies are used to understand how visitors interact with the website. Which of the following has highest boiling point H2O H2S H2Se? 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. however, in the chemistry textbook version 6 p. 484, h2se is expected to be a stronger acid than h2s because h2se has weaker bonds. The phase diagram of hydrogen sulfide is shown below the table. A-level Study and Revision Groups 2022-2023, The Current Year 12 Chat Thread (2022-2023). vaporized on boiling consisting on average of several water Which of the following has highest boiling point H2O H2S? 2%. H2S < H2Se < H2Te < H2O This is the correct boiling point order. Why is the boiling point of hydrogen always higher? Hard Solution Verified by Toppr Because of decrease in bond dissociation enthalpy, acidity of hydrides increases down the group. 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.

This cookie is set by GDPR Cookie Consent plugin. Also, hydrogen sulfide has weaker intermolecular forces (dipole forces, vander waals forces) compared to water resulting in a lower melting point and boiling point. asked Mar 12, 2019 in Chemistry by Daisha (70.9k points) s-block . This cookie is set by GDPR Cookie Consent plugin. Is this a good move to take both? Chemistry. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. H2O < H2S < H2Se < H2Te Therefore, the boiling point of H2O is expected to be the lowest. 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. This is a result of the significant hydrogen bonding present in the water molecule. Sulfur is not from these elements, therefore the dipole-dipole force between 2H2S is not a hydrogen bond. Among H2S, H2Se, H2Te the strongest acid is H2Te. Fher, F. In "Handbook of Preparative Inorganic Chemistry"; Brauer, E., Ed. It is heavier than air and tends to accumulate at the bottom of poorly ventilated spaces. H 2O:100 C; H 2S: 60 C; H 2Se: 41.25 C; H 2T e: 2.25 C. A related reaction involves the acid hydrolysis of FeSe.[9]. Necessary cookies are absolutely essential for the website to function properly. The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. They both have dipole-dipole which I think are the same strength. So the actual trend here is H2S H2S < H2Se < H2Te < H2O Thi O This is the correct boiling point order. (a) CH3CH2OH and CH3CH2CH2CH2CH2CH2CH3 (b) CH3CH2CH2CH2CH2CH2CH3 and . 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. 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 is more electronegative in H2O or H2S? of H 2O is much higher than that of H 2S. Boiling point of H2S is about -76 deg.

And which explanation would be correct? This is because of the lower electronegativity of sulphur than oxygen. At the critical point there is no change of state when pressure is increased or if heat is added. Liquids have much higher densities in comparison to gases. molecules rather than only one. 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. Hydrogen sulfide is a colorless gas with an offensive stench and is said to smell like rotten eggs. 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. 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.

H2Se gas is used to dope semiconductors with selenium. This cookie is set by GDPR Cookie Consent plugin. This hydrogen chalcogenide is the simplest and most commonly encountered hydride of selenium. It is suspected that this is due to the gas' tendency to oxidise to form red selenium in mucous membranes; elemental selenium is less toxic than selenides are. 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. Hydrogen sulfide provides sulphur source to copper indium gallium film to adjust the light absorption bandgap in chalcogenide thin film photovoltaics. LDS forces do contribute to a higher boiling point and therefore a stronger molecule. It is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent.

The next hydride would be H 2 O (WATER!). At 1atm, the melting point of H2O(water) is 0 degrees celcius and the boiling point is 100 degrees celcius. 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. However, at low temperature and/or high pressures the gas becomes a liquid or a solid. [10] H2Se can be purchased in cylinders.
