Which one hydrogen sulphide H2S or hydrogen selenide H2Se would be expected to have the higher boiling point? H2S has the lowest boiling point. 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. At the critical point there is no change of state when pressure is increased or if heat is added. This hydrogen chalcogenide is the simplest and most commonly encountered hydride of selenium.H 2 Se is a colorless, flammable gas under standard conditions. 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. 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. These bonds require a lot of energy before they will break. 2 Does H2O or H2Se have a higher boiling point? The cookies is used to store the user consent for the cookies in the category "Necessary". The next hydride would be H 2 O (WATER!). Why boiling point of H2O is higher than H2S and H2Se? The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. Hydrogen sulfide is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent. Amongst H2O, H2S, H2Se and H2Te, the one with the highest boiling point is (a) H2O because of hydrogen bonding. 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 The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional".
