Why water has a high boiling point compared with hydrogen sulfide a compound with a similar structure?
Water has a higher boiling point than hydrogen sulfide because water molecules are held together by stronger hydrogen bonds, compared to the weaker dispersion forces between hydrogen sulfide molecules. The presence of hydrogen bonding in water increases its intermolecular forces, requiring more energy input to break these bonds and raise the temperature to the boiling point.
Is hydrogen sulfide a solid at standard room temperature and pressure?
No: hydrogen sulfide is a gas at standard room temperature and pressure
Why is there a difference in boiling points between h2o and h2s?
The difference in boiling points between water (H2O) and hydrogen sulfide (H2S) is primarily due to differences in molecular structure and intermolecular interactions. Water molecules form stronger hydrogen bonds compared to hydrogen sulfide molecules, leading to a higher boiling point for water. Additionally, water molecules are more polar compared to hydrogen sulfide molecules, which also contributes to the difference in boiling points.
Why is hydrogen sulphide a gas at room temp?
Hydrogen sulfide is a gas at room temperature because it has a low boiling point of -60.3°C. This means that at room temperature (usually around 20-25°C), hydrogen sulfide remains in its gaseous state.
Why H2O is liquid and H2S is gas?
Water (H2O) is a liquid at room temperature because of its strong hydrogen bonding, which gives it a higher boiling point compared to hydrogen sulfide (H2S). Hydrogen sulfide is a gas at room temperature due to weaker van der Waals forces between its molecules, resulting in lower boiling point leading to its gaseous state.
Why's the boiling point of hydrogen sulfide slightly higher than hydrogen selenide?
Sulfur is not nearly as electronegative as oxygen so that hydrogen sulfide is not nearly as polar as water. Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water.
What hydride of chalcogen have least boiling point?
Hydrogen sulfide (H2S) has the lowest boiling point among the hydrides of the chalcogen group (oxygen, sulfur, selenium, and tellurium). This is because hydrogen sulfide is a smaller molecule with weaker intermolecular forces compared to the other chalcogen hydrides.

What is the boiling point for iron sulfide?
The boiling point of iron sulfide (FeS) is approximately 1,404 degrees Celsius (2,559 degrees Fahrenheit).
Is hydrogen sulfide a solid?
This largely depends on the pressure and temperature that the Hydrogen Sulfide is at. However, at room temperature hydrogen sulfide is a gas. At normal pressure it condenses to liquid at -60 °C (boiling point) and solidifies at -80 °C (melting point).

What do you think its boiling point would be if water molecules were notpolar molecules?
If water molecules were not polar, their boiling point would likely be lower than the current boiling point of 100°C. The presence of hydrogen bonding between polar water molecules contributes to their high boiling point, so without this interaction, the boiling point would be reduced.
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.
What is the boiling point of hydrogen?
The boiling point of hydrogen is -252.87 degrees Celsius or -423.17 degrees Fahrenheit.
