The (unusually) high boiling point of H2O is explained by extensive hydrogen bonding in water. 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. Which has a higher boiling point between H2O or H2Se? 7 Which of the following has lowest boiling point H2O H2S H2Se? . 10 Why does water have a higher boiling point than hydrogen selenide? Thus, the boiling point of H2S is lower than that of H2O. 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.

Clearly, the dominant intermolecular force is hydrogen bonding, which is expressed most strongly in "water". H2S < H2Se < H2Te < H2O This is the correct boiling point order. [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. These cookies ensure basic functionalities and security features of the website, anonymously. 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?

As for these conflicting explanations, stronger bonds make boiling point greater and conversely, pH higher (less acidic). 5 Why does H2S has lower boiling point than H2Se? LDS forces do contribute to a higher boiling point and therefore a stronger molecule. What does it mean that the Bible was divinely inspired? H2S molecules are involved in weaker hydrogen bonding than H2O molecules. Answer (1 of 14): Summary; Oxygen is more electronegative than sulphur Thus, the dipoles (which have a lot to do with bonding) are more strongly charged in H2O Thus the intermolecular bonds formed in H2O are stronger Thus it takes more energy to break those bonds in H2O Thus, to break those . [7], Industrially, it is produced by treating elemental selenium at T>300C with hydrogen gas. It is the most toxic selenium compound[3] with an exposure limit of 0.05 ppm over an 8-hour period.

History Hydrogen sulfide has been known since early times. When I was much younger, I worked in an inorganic lab whose specialty was inorganic sulfides and selenides. Therefore, despite the fact that HCl molecules can form stronger hydrogen bonds between themselves, the intermolecular attractions between H2S molecules still prevail as they are twice as numerous. Hydrogen selenide is an inorganic compound with the formula H 2 Se. Fher, F. In "Handbook of Preparative Inorganic Chemistry"; Brauer, E., Ed. However, in the chemistry textbook version 6 p.484, H2Se is expected to be a stronger acid than H2S because H2Se has weaker bonds. H2S molecules are involved in weaker hydrogen bonding than H2O molecules. 2 Why boiling point of H2O is higher than H2S and H2Se? Even at extremely low concentrations, this compound has a very irritating . And we all know that the boiling point of water is 100C. 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. -86.31F (-65.73C) This hydrogen chalcogenide is the simplest and most commonly encountered hydride of selenium.
