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. Which is more electronegative in H2O or H2S?

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. It adds across alkenes. Liquids have an indefinite shape and assume the shape of their container. [8][12], Despite being highly toxic, no human fatalities have yet been reported. 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 than H2S does. Similarly, it is asked, which has the highest boiling point h2o h2s or H2Se? Boiling pointH2S : 60 C (76 F; 213 K)H2Se : 41.25 C (42.25 F; 231.90 K), which is 18.75 C higher (values from wikipedia - date: 09-09-2014) What is the compound name for H2Se? Among H2O, H2S, H2 Se and H2 Te the one with highest boiling point. 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. But opting out of some of these cookies may affect your browsing experience. however, in the chemistry textbook version 6 p. 484, h2se is expected to be a stronger acid than h2s because h2se has weaker bonds. 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 .

[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. Hydrogen selenide is an inorganic compound with the formula H2Se. Which is correct poinsettia or poinsettia? It is heavier than air and tends to accumulate at the bottom of poorly ventilated spaces. It is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent. Bond angle of H2O is larger because oxygen is more electronegative than sulphur therefore bond pair electron of OH bond will be closer to oxygen and there will be more bond-pair bond-pair repulsion between bond pairs of two OH bonds. The boiling point of hydrogen compounds of group 16 is into the order of H2O > H2S . Is H2Te stronger than H2Se? 1 answer.

H 2 S < H 2 S e < H 2 T e Therefore, the correct order of boiling point is: H 2 S < H 2 S e < H 2 T e < H 2 O Hence, the correct option is (A) 1. This in turn will increase the energy needed to pull the molecules apart, thus an increase in the boiling point . 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. In water, the hydrogens are bound to oxygen, a strongly electronegative element. When I was much younger, I worked in an inorganic lab whose specialty was inorganic sulfides and selenides.

JavaScript is disabled. 4 When compared to H2S H2O has a higher boiling point because H2O contains stronger? Compare the boiling point of CH3 and CCl4 Both same shape and non polar Since CCl4 has more e's then stronger LDFs = higher bp Compare the bp of pentane and neopentane Same e's different shape Linear pentane has higher surface area for instantaneous attractions = higher BP Branched shape of neopentae decrease LDFs Forget about the intramolecular forces so much. There are 2 factors that affect this problem. Also, hydrogen sulfide has weaker intermolecular forces (dipole forces, vander waals forces) compared to water resulting in a lower melting point and boiling point. Thus, the boiling point of H2S is lower than that of H2O. Begin typing your search term above and press enter to search.

As for these conflicting explanations, stronger bonds make boiling point greater and conversely, pH higher (less acidic). So, less energy is required to break the hydrogen bonds in H2S. H2S has the lowest boiling point. Water molecules are in associated state. 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. What does it mean that the Bible was divinely inspired? Since S, Se, Te are in the same group of the periodic table - so they have the same type of forces/bonding. Hydrogen sulfide provides sulphur source to copper indium gallium film to adjust the light absorption bandgap in chalcogenide thin film photovoltaics. -42.25F (-41.25C) Amongst H2O, H2S, H2Se and H2Te, the one with the highest boiling point is (a) H2O because of hydrogen bonding. Google use cookies for serving our ads and handling visitor statistics.
