The H-S bonds in H2S are weaker than the H-O bonds in H2O, therefore H2S gives up a proton (H+) more easily than H2O, making it a better acid. Hydrogen sulfide is slightly denser than air; a mixture of H 2 S and air can be explosive. H 2 O, which is known to all as water, is something without which we cannot live. In Water, the oxygen atom is highly electronegative and can polarize (partially) the hydrogen atoms, thus hydrogen-hydrogen bonds between the H2O molecules can be formed creating a very high boiling point. H2O vs H2O2 | Water vs Hydrogen Peroxide Properties, Usage, Difference Water (H 2 O) and hydrogen peroxide (H 2 O 2) are molecules of oxygen and hydrogen elements. The bond energy of H2Se is less than H2S, making it easier for the hydrogen atom to leave the molecule. )H2S is neutral so it doesn't seem like it would have any extra electrons to donate. Si tu compares les pka: On a pour H2O/OH->14 et pour H2S/HS-~ 7. 2.) H 2 S est donc plus acide (faible) que H 2 O. L'energie de la liaison H-O est plus forte que celle de H-S. Dernière modification par vpharmaco ; 29/09/2011 à 12h47. In which series are the substances H2O, H2S, H2Se and H2Te are arranged in the order of increasing boiling point? H2S Awareness is a course designed specifically for workers whose workplace puts them in situations of risk of H2S exposure but they are not workers in the upstream oil or gas sector. These workers might instead work in mines, on farms or at water treatment plants. (A portion of the periodic table is shown on the other side) A. H2O < H2S < H2Se < H2Te B. H2Te < H2Se < H2S < H2O C. H2O < H2Te < H2Se < H2S D. H2S < H2Se < H2Te < H2O … Hydrogen Sulfide (H2S) is a gas commonly found during the drilling and production of crude oil and natural gas, plus in wastewater treatment and utility facilities and sewers. The gas is produced as a result of the microbial breakdown of organic materials in the absence of oxygen. In H2S those bonds don’t exist, because sulfur is much less electronegative. H2S is only acidic in reference to water(!). H2 molecule is the least polar. These workers might instead work in mines, on farms or at water treatment plants.
In general, hydrogen sulfide acts as a reducing agent, especially in the presence of base, which forms SH −. But in H2S the bond angle is around 92 degrees. Compare H2O and H2S Post by Chem_Mod » Sun Aug 21, 2011 6:55 pm According to the solution manual H20 is more basic or is a stronger Lewis base than H2S because oxygen is more electronegative than S and has a higher partial negative charge. This additional hydrogen bonding keeps H2O a liquid up to 100C where H2S is a gas at room temperature.

1. Between H2O and H2S, the most polar will be H2O as oxygen is more electronegative than sulphur. Why bond angle of Hydrogen sulphide (H2S) is smaller than water (H2O) ? Two hydrogens are covalently bonded to oxygen to form water. Chemistry Explorers 19,045 views Both molecules are polar and exhibit dipole-dipole attractions, but in addition, water exhibits stronger hydrogen bonding. H2S Awareness is a course designed specifically for workers whose workplace puts them in situations of risk of H2S exposure but they are not workers in the upstream oil or gas sector. - Duration: 3:37. Of coarse H2O is neutral referred to water because it is the S A M E . Colorless, flammable, poisonous and corrosive, H2S gas is noticeable by its rotten egg smell.
