Which of the following has highest boiling point H2O H2S? Compare the boiling point of CH3 and CCl4 Both same shape and non polar Since CCl4 has more e's then stronger LDFs = higher bp Compare the bp of pentane and neopentane Same e's different shape Linear pentane has higher surface area for instantaneous attractions = higher BP Branched shape of neopentae decrease LDFs You also have the option to opt-out of these cookies. Bigger london dispersion forces do lead to higher boiling points when a molecule exhibits no hydrogen bonds, is not polar or when the polarity is almost the same between two molecules. Study with Quizlet and memorize flashcards containing terms like Arrange these compounds in order of increasing boiling point H2S, H2Se, H2O (a) H2O < H2Se < H2S (b) H2Se < H2S < H2O (c) H2Se < H2O < H2S (d) H2S < H2Se < H2O (e) H2O < H2S < H2Se, Which of the following would be expected to form a homogenous solution? Hydrogen sulfide, H2S, is ahighly toxic and flammable, colorless gas with a characteristic odor of rotten eggs. The effect of hydrogen bonding is significantly less for the other elements of the chalcogenide group. H2S molecules are involved in weaker hydrogen bonding than H2O molecules. Knowing that hydrogen bonds are stronger than dipole-dipole forces, this leads to : water has a higher boiling point than hydrogen sulfide because hydrogen bonds are much stronger than dipole-dipole bonds.

Langner "Selenium and Selenium Compounds" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. This is because of the lower electronegativity of sulphur than oxygen. So, less energy is required to break the hydrogen bonds in 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. Since S, Se, Te are in the same group of the periodic table - so they have the same type of forces/bonding. Thus, the boiling point of H2S is lower than that of H2O. It adds across alkenes.

This cookie is set by GDPR Cookie Consent plugin. Why does H2S has lower boiling point than H2Se? 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. Boiling point of H2S is about -76 deg. I will try to give u a most appropriate and short answer that u can understand easily See h20 has 104.5 degrees bond angle , h2s has 92degrees , h2se has 91degrees and h2te has 90degrees bond angles Draw diagrams of these u will find all of them have tetrahedral shape with 2 lone pairs , assume that no hybridization occurs and all these central . 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.

Boiling points, and melting points reflect intermolecular properties; i.e. 15%, H2Sebecause of lower molecular weight. 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. In water, the hydrogens are bound to oxygen, a strongly electronegative element. The oxygen atom polarizes electron density away from the bond to give "^(delta+)H-O^(delta-)-H . Clearly, the dominant intermolecular force is hydrogen bonding, which is expressed most strongly in "water". Hydrogen selenide is an inorganic compound with the formula H2Se. Solve any question of Hydrogen with:-. 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.
