Why does water have a higher boiling point than H2Se? Hydrogen selenide/Boiling point. And which explanation would be correct? Hydrogen sulfide, H2S, is ahighly toxic and flammable, colorless gas with a characteristic odor of rotten eggs. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. 6 Which is more electronegative in H2O or H2S? 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. Chemistry. Thus, the boiling point of H2S is lower than that of H2O. 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 .

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. 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. The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies. 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 . 10 What is the melting point of hydrogen sulfide?

LDS forces do contribute to a higher boiling point and therefore a stronger molecule. Liquids have a definite volume. Hydrogen selenide is hazardous, being the most toxic selenium compound[3] and far more toxic than its congener hydrogen sulfide. Liquids have much higher densities in comparison to gases. Since S, Se, Te are in the same group of the periodic table - so they have the same type of forces/bonding. How do you win an academic integrity case? 5 Why does H2Se have a higher boiling point than H2S? -42.25F (-41.25C) However, at low temperature and/or high pressures the gas becomes a liquid or a solid.
