WebWhy H2O is liquid but H2S is a gas? Oxygen has smaller size and higher electronegativity as compared to sulphur. Therefore, there is extensive hydrogen bonding in H 2 O, which is absent in H 2 S. Molecules of H 2 S are held together only by weak van der Waal's forces of attraction. Hence, H 2 O exists as a liquid while H 2 S as a gas.

WebThe balanced reaction can be given as: 2 H 2 S ( g) + SO 2 ( g) → 3 S ( s) + 2 H 2 O ( l) ( Hydrogen sulphide) ( Sulphur dioxide) ( Sulphur) ( Water). Oxidizing agent: Here, Sulphur dioxide ( SO 2) acts as Oxidizing agent because it loses Oxygen atom and get reduced to S (Sulphur) therefore, it acts as Oxidizing agent. Web1. Strong acids are listed at the top left hand corner of the table and have Ka values >1 2. Acid with values less than one are considered weak.
WebDec 10, 2024 · Strengths of H2S vs H2Se. 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. However, in the chemistry textbook version 6 p.484, H2Se is expected to be a stronger acid than H2S because H2Se has weaker bonds. WebApr 3, 2012 · 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. Is h2s a polar …
WebMar 23, 2011 · 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. What is the name of the acid H2Se? Hydrogen Selenide. WebThis problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: Why is H2S a stronger nucleophile than H2O in an aprotic solution? Shouldn't it be the opposite since nucleophile strength increases up the group in aprotic because of base strength and down the group in protic ...
WebAnswer (1 of 6): Water is an acid. I'm an organic chemist, and we often work with things toward which water is a pretty strong acid. Water is not as acidic as HF or H2S. HF is more acidic than water because F is more electronegative than O; therefore F^- is a weaker base than OH^-. H_2S is mor...
