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. The strength of LDFs depends on polarizability. [10] H2Se can be purchased in cylinders. Among H2O, H2S, H2 Se and H2 Te the one with highest boiling point. A teacher walks into the Classroom and says If only Yesterday was Tomorrow Today would have been a Saturday Which Day did the Teacher make this Statement? H2Te has the highest molecular weight and thus it has the highest boiling point from H2S and H2Se. Question: O CBr <CaBr <NBry<Br2 Question 10 Rank the following in order of increasing predicted boiling point: H2, H20, H2S, H25e 1 = lowest boiling point: 4 = highest boiling point H2 = [Select] H2O = Select] Has Select . Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water. However, in the chemistry textbook version 6 p.484, H2Se is expected to be a stronger acid than H2S because H2Se has weaker bonds.

The cookie is used to store the user consent for the cookies in the category "Other. LDF is found in every bond because its the most basic form of molecular attraction. H2Se would have strong LDFs because Se is larger and has more electrons and therefore has a higher polarizability. The correct boiling point order is: A H 2S<H 2Se<H 2Te<H 2O B H 2O<H 2Se<H 2S<H 2Te C H 2Te<H 2Se<H 2S<H 2O D H 2O<H 2S<H 2Se<H 2Te Medium Solution Verified by Toppr Correct option is A) True (1) 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. It is the most toxic selenium compound[3] with an exposure limit of 0.05 ppm over an 8-hour period. molecules rather than only one. Top Steph Du 1H Is this a good move to take both?

[6], The properties of H2S and H2Se are similar, although the selenide is more acidic with pKa = 3.89 and the second pKa = 11,[6] or 15.05 0.02 at 25C. However, it is observed that the boiling point of H2O is highest among these hydrides. However, in the chemistry textbook version 6 p.484, H2Se is expected to be a stronger acid than H2S because H2Se has weaker bonds. SOAS Paul Robeson House - what's it like? 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 .

One more up and you find that H 2 S (hydrogen sulfide) has a boiling point at -62C. That means H2O is supposed to have a lower boiling point then H2S, but the opposite can be observed and thus be explained by the formation of strong hydrogen bonds. Thus, the boiling point of H2S is lower than that of H2O. Similarly, it is asked, which has the highest boiling point h2o h2s or H2Se? This may be a dumb question, but I was wondering about this question from Matthew Nguyen's UA Worksheets? Hydrogen selenide is an inorganic compound with the formula H 2 Se.
