Water has a higher boiling point than hydrogen sulphide. H2S is more polar than H2Se because H2S has greater dipole-dipole forces than H2Se since the H-S bond is more polar than the H-Se bond. 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 . These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. 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.

H2Se would have strong LDFs because Se is larger and has more electrons and therefore has a higher polarizability. Molecules with hydrogen bonds will always have higher boiling points than similarly sized molecules which dont have an an -O-H or an -N-H group. Sulfur is not from these elements, therefore the dipole-dipole force between 2H2S is not a hydrogen bond. 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. Why is H2Se have a higher boiling point than H2S? What is the melting point of hydrogen sulfide? Hydrogen selenide is hazardous, being the most toxic selenium compound[3] and far more toxic than its congener hydrogen sulfide. Why bond angle of H2O is higher than H2S? It is suspected that this is due to the gas' tendency to oxidise to form red selenium in mucous membranes; elemental selenium is less toxic than selenides are. 9 Which has a higher boiling point H2O or H2S? asked Apr 21, 2019 in Chemistry by Simrank (72.5k points) p - block element . 1 Why boiling point of H2O is higher than H2S and H2Se? 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.

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? Analytical cookies are used to understand how visitors interact with the website. Which one hydrogen sulphide H2S or hydrogen selenide H2Se would be expected to have the higher boiling point? Hydrogen sulfide is a colorless gas with an offensive stench and is said to smell like rotten eggs. 2. 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. Thus, the boiling point of H2S is lower than that of H2O. More the boiling point, less the volatility.

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. 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. So despite its small molecular weight, water has an incredibly . What does it mean that the Bible was divinely inspired?

Should fat shaming be allowed to an extent? On the other hand, H2Se and H2Te contain hydrogens that are not attached to electronegative elements, so they cannot undergo hydrogen bonding, and they possess boiling points that are significantly lower than water. H2O molecules undergo hydrogen bonding. Cookies are only used in the browser to improve user experience. Necessary cookies are absolutely essential for the website to function properly. Since electrons are constantly moving, at any given time, one atom will be more electronegative than the other atom. So, less energy is required to break the hydrogen bonds in H2S. [5] Exposure at high concentrations, even for less than a minute, causes the gas to attack the eyes and mucous membranes; this causes cold-like symptoms for at least a few days afterwards.
