The bigger the atom, the greater the shift in electrons to create a temporary dipole and makes H2Se a stronger acid. 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. 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? Hydrogen selenide/Boiling point. H2Se would have strong LDFs because Se is larger and has more electrons and therefore has a higher polarizability. 4.

Does h2s or h2se have a higher boiling point? 4 When compared to H2S H2O has a higher boiling point because H2O contains stronger? 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. You must log in or register to reply here. It is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent. H2S < H2Se < H2Te < H2O This is the correct boiling point order. C. H2O molecules undergo dipole-dipole interaction. However, in the chemistry textbook version 6 p.484, H2Se is expected to be a stronger acid than H2S because H2Se has weaker bonds.

Which is the correct order for boiling point? h2s vs h2se boiling point H2O, 100oC; H2S, -60oC; H2Se, -41oC; H2Te, -2oC (2 marks) Generally, the boiling points in a series increases with the molecular mass and this would put the boiling point of water below -60o C. The boiling point of water is high because of the extensive H-bond between the water molecules. Hydrogen sulfide provides sulphur source to copper indium gallium film to adjust the light absorption bandgap in chalcogenide thin film photovoltaics. And hence, greater will be the boiling point of that liquid. I'm taking A level economics and business studies. Which has a higher boiling point H2O or H2S? Consistent with this structure, three IR-active vibrational bands are observed: 2358, 2345, and 1034cm1. Bond angle of H2O is larger because oxygen is more electronegative than sulphur therefore bond pair electron of OH bond will be closer to oxygen and there will be more bond-pair bond-pair repulsion between bond pairs of two OH bonds.

What is the boiling point of H2Se? H 2Se because of lower molecular weight Medium Solution Verified by Toppr Correct option is A) Among H 2O,H 2S,H 2Se and H 2Te, the one with the highest boiling point is H 2O because of intermolecular hydrogen bonding which leads to molecular association and leads to higher energy for boiling. 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.
