NH3 exhibits hydrogen bonding in addition to dispersion forces. This significantly increases the intermolecular force, and raises the boiling point. PH3 does not exhibit hydrogen bonding and the dominant intermolecular force holding these molecules together is dispersion forces. (Dispersion forces also known as Van Der Waal Force)

This phenomenon is generally ascribed to the much stronger hydrogen bonding between molecules that occurs at equilibrium in liquid ammonia. The hydrogen bonding is strong enough that the effective kinetic molecular unit in liquid ammonia has a higher mass than the effective kinetic molecular unit in liquid phosphine, even though the mass of a single molecule of phosphine is greater than the mass of a single molecule of ammonia.
iodine is having higher boiling point
Because of its hydrogen bonding.
boiling point:1382 C Melting point: 605 C
ethanol has a higher boiling point- of 78°C :)
Ammonia is a compound of Hydrogen and Nitrogen(NH3). It is normally found as a stinky, lighter than air, gas.Therefore at 'room temperature' it melting point is approximately -77C, and its boiling point -33C. Its low density and atomic weight set its phase change points.
Boiling point of NH3: -33,34 0C Boiling point of NF3: -129,1 0C The boiling point of ammonia is higher.
Yes, Boiling point of ammonia, NH3: - 33,34 0C Boiling poit of methane, CH4: - 161,6 0C
it doesn't
The boiling point of ammonia at atmospheric pressure is -33.34oC.
The meaning is at what temperature does ammonia melt at and what temperature does ammonia boil at? for eg. waters melting point is 0 degrees celcius and the boiling point of water is 100 degrees celsius
Ammonia: -33,34 0C Nitrogen trifluoride: -129 0C
If you mean ammonia, the melting point of ammonia is −77.73 °C, and its boiling point is −33.34 °C. (Wikipedia)
nitrogen is more electronegative than the other elements, so there is a molecular dipole towards the nitrogen. NH3 is the most polar of the three.
Hydrogen bonding
Chlorine has higher boiling point.
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
The boiling point is higher.
