(Chemical Discovery and Invention in the Twentieth Century, Sir William Tildon, 1917). The ability to form large numbers and networks of hydrogen bonds is responsible for many of the unique properties of water including its relatively high melting point, boiling point, heat capacity, viscosity, and low vapor pressure. This is 18% greater than that of air. Water has a higher boiling point than hydrogen sulfide because the hydrogen bonding in water is quite different, and hydrogen sulfide does not have hydrogen bonding at all. The table shows the same numbers together with the molecular weight and density, as well as the numbers of carbon, hydrogen and sulfur in the molecules. You should look up the boiling points of H_2O, H_2S, H_2Se, H_2Te. Hydrogen sulfide and water boil at -60.7 oC and +100.0 oC , respectively. These bonds require a lot of energy before they will break. In fact, the Chemistry Building at the University of Illinois in 1915 had a built-in supply of hydrogen sulfide to the various labs, i.e., H2S 'on tap'! Sulfur is not nearly as electronegative as oxygen so that hydrogen sulfide is not nearly as polar as water. â¦, wahan hogi jo aa ske most welcome jo na aa ske wo bhaad mein jaaye ..xDâ, calculate the no.pf atoms present in 40 g of sulphur....given atomic mass of S is 32, At equilibrium the amounts of N2O4 and N2 in a 3 liters flask are 7.64g and 1.56g The oxygen atom polarizes electron density away from the bond to â¦ 2 < = = > SO. ). - 17059792 1. When rationalising boiling point differences, the first consideration is always the strength of the intermolecular forces between the molecules in the liquid.
