Also question is, why does h2o have a higher boiling point than ch4?
Water has a higher boiling point because the hydrogen bonds that form among water molecules are stronger than the Van der Waals interactions among methane molecules, thus more energy must be provided in order to break the hydrogen bonds and allow the water molecules to escape the liquid state.
Furthermore, what has a lower boiling point than water? Nitrogen (N2), carbon dioxide, oxygen (O2), helium, chlorine (Cl2) and hydrogen are all familiar examples of substances that boil at much lower temperatures than water. Liquid helium has the lowest boiling point of all — about -452 degrees Fahrenheit, only 4.2 degrees Celsius above absolute zero.
Also know, does ch4 or SnH4 have a higher boiling point?
Therefore, CH4 is expected to have the lowest boiling point and SnH4 the highest boiling point. It all flows from this general principle: as bonds become more polarized, the charges on the atoms become greater, which leads to greater intermolecular attractions, which leads to higher boiling points.
Why is the boiling point of CCl4 higher than ch4?
CCl4 would be expected to have a higher boiling point than CH4 since it possesses more electrons than CH4.. Thus the magnitude of the dispersion forces present between CCl4 molecules is greater than that between CH4 molecules, and this is the main reason for the higher boiling point.
