Why does H2O have a boiling point higher than H2S?
Water (H20) has hydrogen bonding and London forces. Hydrogen sulfide (H2S) has only London forces. The reason why water has hydrogen bonding and hydrogen sulfide does not is because the oxygen in water is more electronegative than the sulfur in hydrogen sulfide. Hydrogen bonding only occurs between molecules that have hydrogen bonded to a very electronegative atom, which is either oxygen, fluorine, or nitrogen.Think about it: a hydrogen bond is a intermolecular attraction between the hydrogen of one atom and the lone pair of electrons of another atom. In order for the bond to exist the lone pair of electrons must belong to a electronegative atom, so there will be a great tendency for attraction.H2O is very strongly hydrogen bonded. These bonds require energy to break resulting in a higher boiling point.
Why water has a high boiling point compared with hydrogen sulfide a compound with a similar structure?
Hydrogen bonding is a very strong intermolecular attraction for one water molecule to another. Hydrogen sulfide, because of the lower electronegativity of sulfur does not have hydrogen bonding. This strong attraction must be overcome to make the substance boil.
The molecular formula for hydrogen sulfide is H2S. What does the formula indicate about the composition of a 1.0-gram sample of hydrogen sulfide?
All of the molecules are identical combinations of two hydrogen atoms and one sulfur atom.
The molecular formula for hydrogen sulfide is H2S. What does the formula indicate about the composition of a 1.0 gram sample of hydrogen sulfide?
All of the molecules are identical combinations of two hydrogen atoms and one sulfur atom.
What is the product of the reaction between calcium hydroxide and hydrogen sulfide?

What type of bonding is found in hydrogen sulfide?

Why is van de waals forces important?
They are the primary intermolecular attractive forces that act between nonpolar molecules. -Apex.
Are the London dispersion forces between water molecules weaker or stronger than the London dispersion forces between molecules of hydrogen sulfide?
London dispersion force usually pertains to carbon carbon chains. It is a very weak force. For polar molecules the intermolecular force is described as dipole-dipole. Oxygen has a greater electronegativity than sulfur so its dipole-dipole force would be stronger than hydrogen sulfide. Oxygen also has the ability to hydrogen bond which is a pretty strong force.
Which has the highest boiling point H2S or H2Se or H2O?
Water has the highest boiling point, as the hydrogen bonds between the molecules need more energy to break than the hdyrogen bonds in H2S, and H2Se, as Oxygen is much more electronegative than Sulphur of Selenium, so it makes the molecules more polar.
Will hydrogen sulfide explode?
Yes. Hydrogen sulfide is extremely flammable.
What is hydrogen sulfide symbol?
The chemical formula for hydrogen sulfide is H2S.
