Why is the boiling temperature of ph3 greater than ch4? Rank the compounds NH3, CH4, PH3 in order of increasing boiling point. … NH3 is highest because the N-H bonds give it Hydrogen Bonding Intermolecular Forces. PH3 is next highest because it has dipole dipole forces, which are weaker than “hydrogen bonding” CH4 has neither of those.
Why is the boiling point of CH4 is much lower than that of NH3? The intermolecular attractive forces occurring in, CH4 are only London dispersion forces. Hydrogen-bonding attractive forces are stronger forces compared to dispersion forces when atoms are in the second period. Therefore, NH3 has a higher boiling point compared to CH4.
Why PH3 has higher boiling point than NH3? NH3 molecules makes strong intermolecular H bonding b/w themselves. But due to lesser electronegativity of larger PH3 molecules, they cannot form Hydrogen Bonding b/w themselves. In NH3, there is hydrogen bonding whereas in PH3 there is no hydrogen bonding. Therefore, the NH3 has higher boiling point than PH3.
Why is the boiling point of water higher than CH4? Because oxygen is more electronegative than carbon, an O-H bond has a larger bond dipole than a C-H bond. Hence the force of attraction between two water molecules is greater than it is between two methane molecules. Water has the higher boiling point. … Therefore, methane has the higher boiling point.

Why does my stomach sound like it’s boiling?
Stomach growling occurs as food, liquid, and gas go through the stomach and small intestine. Stomach growling or rumbling is a normal part of digestion.
