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? Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. C. H2O molecules undergo dipole-dipole interaction. 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. Water has a higher boiling point than hydrogen sulphide. It is heavier than air and tends to accumulate at the bottom of poorly ventilated spaces. We also use third-party cookies that help us analyze and understand how you use this website. 7 Which of the following has lowest boiling point H2O H2S H2Se? 11 Which is the correct order for boiling point? You are using an out of date browser. Hard Solution Verified by Toppr Because of decrease in bond dissociation enthalpy, acidity of hydrides increases down the group. H2Te has the highest molecular weight and thus it has the highest boiling point from H2S and H2Se. Molecules with hydrogen bonds will always have higher boiling points than similarly sized molecules which dont have an an -O-H or an -N-H group. The selenide, in contrast, forms 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.

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.

Interionic and Intermolecular Forces (Ion-Ion, Ion-Dipole, Dipole-Dipole, Dipole-Induced Dipole, Dispersion/Induced Dipole-Induced Dipole/London Forces, Hydrogen Bonding), Register Alias and Password (Only available to students enrolled in Dr. Lavelles classes. H2S is more polar than H2Se because H2S has greater dipole-dipole forces than H2Se since the H-S bond is more polar than the H-Se bond. 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. Which has higher boiling point H2O or H2S explain?

Similarly, it is asked, which has the highest boiling point h2o h2s or H2Se? -42.25F (-41.25C) only weak hydrogen bonds; therefore, its average "effective" 1. [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. In water, the hydrogens are bound to oxygen, a strongly electronegative element. 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. Patterns of problems. 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 Who wrote the music and lyrics for Kinky Boots? 4 When compared to H2S H2O has a higher boiling point because H2O contains stronger? .

If true enter 1 else 0. H2O molecules can pack together more closely. These bonds require a lot of energy before they will break. In the laboratory, H2Se is usually prepared by the action of water on Al2Se3, concomitant with formation of hydrated alumina. Since S, Se, Te are in the same group of the periodic table - so they have the same type of forces/bonding. Q. Amongst H2O,H2S,H2Se and H2Te, the 1one with the highest boiling point is. This is because of the lower electronegativity of sulphur than oxygen. Thus, there will always be some degree of induced dipole-induced dipole (also known as LDF).
