H2Se is a colorless, flammable gas under standard conditions. 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. Why is H2Se stronger than H2S? Analytical cookies are used to understand how visitors interact with the website. This problem has been solved! Hydrogen selenide/Melting point. Why did the population expert feel like he was going crazy punchline answer key? Safe with 3, or risk 4?

However, at low temperature and/or high pressures the gas becomes a liquid or a solid. 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. H2Se adopts a bent structure with a HSeH bond angle of 91[citation needed]. H2Te because of higher molecular weight. 9 Which has a higher boiling point H2O or H2S? What are the disadvantages of shielding a thermometer? Liquids are not easily compressed. It is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent. 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. the strong hydrogen bonding of water gives it a higher "effective" 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.

They both have dipole-dipole which I think are the same strength. (1) The hydrogen bonding ability of H 2 O which increases the boiling point.The partial charges, induced by the higher electronegativity of oxygen, mean that the hydrogens and oxygens will be attracted to one another by coloumbic forces. For example, water boils at 100 C (212 F) at sea level, but at 93.4 C (200.1 F) at 1,905 metres (6,250 ft) altitude. What are the main properties of liquids (in contrast to gases and solids)?
