PH3 has lowerboiling point than NH3. Why? This is due to the fact that NH3 has hydrogen bonding which increase the bond strenth and thus increase the boiling point. While in case of PH3 no hydrogen bonding is possible.

Does NH3 or PH3 have a higher boiling point?

Ammonia, NH3, has a much higher boiling point than phosphine, PH3.

Why does PH3 have lower 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 the boiling point of PH3 is less than that of NH3 and AsH3?

AsH3 is a larger molecule than PH3 as As is lower down the periodic table, so has a higher atomic number so more electrons. Therefore AsH3 has more electrons than PH3 meaning that the instantaneous dipole produced by AsH3 is greater.

Which one has the lowest boiling point PH3?

The higher boiling point of NH3 is due to excessive hydrogen bonding, so PH3 have lowest boiling point among hydrides of group number 15, i.e. nitrogen family.

Which of the following has lowest boiling point PH3?

Solution : In ammonia, `(NH_(3))` the molecules are linked by intermolecular hydrogen bonding which is absent in the molecules of phosphine `(PH_(3))`. Therefore, boiling point of `PH_(3)` is less than that of `NH_(3)`. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.

Which has the highest boiling point NH3 PH3 AsH3 SbH3?

Answer: From the question NH3 will have highest boiling point among the following since the NH3 has the ability to form hydrogen bonds.

Which has stronger intermolecular forces PH3 or NH3?

Although PH3 is a larger molecule with greater dispersion forces than ammonia, NH3 has very polar N-H bonds leading to strong hydrogen bonding. This the dominant intermolecular force and results in a greater attraction between NH3 molecules than there is between PH3 molecules.

Which has the lowest boiling point NH3 PH3 AsH3 SbH3?

Hence correct order of boiling point is: H2O > SbH3 > NH3 > AsH3 > PH3.

Which one has the lowest boiling point a NH3 B PH3 C?

PH3 has lower boiling point than NH3 .

Why does the boiling point increase from PH3 to SbH3?

Answer. Due to increase in size of central atom from N to Sb, the van der Waals forces increase. Therefore boiling point of SbH3 is more than that of NH3.

Why boiling point of NH3 is greater than AsH3?

Correct Option d PH3

Which has the higher boiling point NH3 or AsH3?

In the case, of AsH3, even this molecule is gas at room temperature and its boiling point should be greater than NH3, but this is not the case and NH3 has a higher boiling point than AsH3.

Which has the highest boiling point?

Xenon has the highest boiling point.

Which one of the following has highest boiling point?

The more sphere like the molecule, the lower its surface area will be and the fewer intermolecular Van der Waals interactions will operate. Hence C4H9Cl straight chain molecule with the highest number of carbons has the highest boiling point.

What has the lowest boiling point?

The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten.
