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 does not store any personal data. However, you may visit "Cookie Settings" to provide a controlled consent. H2Se is a colorless, flammable gas under standard conditions. The boiling point of hydrogen compounds of group 16 is into the order of H2O > H2S . 2 Why boiling point of H2O is higher than H2S and H2Se? Which is correct poinsettia or poinsettia? Among H2S, H2Se, H2Te the strongest acid is H2Te. 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. 2.

H2O molecules undergo dipole-dipole interaction. H2Te has the highest molecular weight and thus it has the highest boiling point from H2S and H2Se. 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 . H2S < H2Se < H2Te < H2O This is the correct boiling point order. According to the Sonoda method, H2Se is generated from the reaction of H2O and CO on Se in the presence of Et3N. Why water has high boiling and melting point? Water has a higher boiling point than hydrogen sulphide. 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. Chemistry. 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. You can target the Engineering ToolBox by using AdWords Managed Placements. F. The (unusually) high boiling point of H2O is explained by extensive hydrogen bonding in water. Where was the Dayton peace agreement signed? However, I feel like I'm missing something.

Hydrogen sulfide occurs naturally in crude petroleum, natural gas, volcanic gases, and hot springs. Bernd E. Langner "Selenium and Selenium Compounds" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. [8] A number of routes to H2Se have been reported, which are suitable for both large and small scale preparations. These cookies track visitors across websites and collect information to provide customized ads. The bigger the atom, the greater the shift in electrons to create a temporary dipole and makes H2Se a stronger acid. Since S, Se, Te are in the same group of the periodic table - so they have the same type of forces/bonding. Ethyl ether molecules experience only London dispersion forces whereas hydrogen sulfide (H2S) molecules experience dipole forces. Thus, there will always be some degree of induced dipole-induced dipole (also known as LDF). It is the most toxic selenium compound with an exposure limit of 0.05 ppm over an 8-hour period. Why does H2S have a lower boiling point than H2O and H2Se? Thus, the boiling point of H2S is lower than that of H2O. 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. Safe with 3, or risk 4? 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. The oxygen atom polarizes electron density away from the bond to give "^(delta+)H-O^(delta-)-H . F Boiling point of H2O is +212 deg. 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. 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. Consistent with this structure, three IR-active vibrational bands are observed: 2358, 2345, and 1034cm1. 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. So, less energy is required to break the hydrogen bonds in H2S.
