In this video we compare the
boiling points of Ammonia and Phosphine based on their intermolecular forces. Intermolecular forces (e.g. dipole-dipole and Lon. Basicity also decreases in the order
NH3 >
PH3 > AsH3 > SbH3 ≥ BiH3. Due to high electronegativity and small size of nitrogen,
NH3 exhibits hydrogen bonding in solid as well as liquid state. Because of this, it has higher melting and
boiling points than that of
PH3. Table 7.2: Properties of Hydrides of Group 15 Elements. 3 years ago. Bp of
NH3: -33°C ,
PH3: -87°C , AsH3: -62.4°C , SbH3: -18°C. So the increasing order of
boiling point is.
PH3. The regular trend for
boiling point is that it increases down the group due to increase in size and van der waal forces between atoms.But the B.p of ammonia (
NH3) is more than
Ph3 and Ash3.

N H 3 has hydrogen bonds while P H 3 has permanent dipole permanent dipole bonds between P H 3 molecules. Explanation: Both have simple molecular structures, however if you recall, nitrogen is more electronegative than phosphorus and is part of the three special elements, Nitrogen,Oxygen and Fluorine that can participate in hydrogen bonding. Hydrogen bonding is obtained when H atom is attached to electronegative N,O or F atom.
PH 3 has lower
boiling point than
NH 3. In
NH 3, intermolecular hydrogen bonding leads to molecular association. Huge amount of energy is required to break these hydrogen bonds. Hence,
NH 3 has high
boiling point. In
PH 3, no hydrogen bonding is possible. 5 years ago. dear omkar.
NH3 will have the highest
boiling point because
NH3 molecules can form hydrogen bonds with each other. The other molecules will increase in

boiling point!** My question is if A, B & C are dipole-dipole, and D is hydrogen . Chemistry. Hydrogen cyanide is a highly poisonous, volatile liquid. It can be prepared by the following reaction. Explain why
the boiling point of PH3 is lower than
the boiling point of AsH3. AsH3 is a larger molecule than
PH 3 as As is lower down the periodic table, so has a higher atomic number so more electrons. Therefore AsH 3 has more electrons than
PH 3 meaning that the instantaneous dipole produced by AsH 3 is greater.

NH 3 . CH 4. Answer. The
boiling point of
NH3, PH3,AsH3 and SbH3 are respectively -33.4 oC,-87.5 oC, -62.4 oC, -18.4oC. Explain the variation of their
boiling points in terms of the types of intermolecular forces. The
boiling point of
NH3 is higher than that of
PH3. The nitrogen atom is more electronegative (3·0) than phosphorus (2·1). As a result,
NH3 exhibits intermolecular hydrogen bonding while
PH3 does not show any hydrogen bonding. Thus, extra energy is needed to break these hydrogen bonds in
NH3. Thus,
NH3 has higher
boiling point than
PH3. the
boiling point of
nh3 is higher than the
boiling point of
ph3 explain - Chemistry - TopperLearning.com | tdyjy488.
NH3 Has a Higher EN than
PH3 and will exhibit Hydrogen bonding. Because of this,
NH3 has a stronger bond with
PH3 so its
boiling point is higher (harder to break bonds, more temperature required).
NH3 is a polar molecule, so the molecules attract each other like magnets.CH4 is completely symmetrical, so it is non polar.Therefore,
NH3 has a higher
boiling point because it takes more energy to. Molar mass of
PH3 = 33.997581 g/mol. The trend in
boiling points for HCl, HBr and HI is shown in your text, Figure 16.4, Pg. 749. It shows that HI has the higher
boiling point. In this case, HCl, HBr and HI all have dipoles, but LDF forces appear to be more important in determining the
boiling point than the relative dipole forces.
The Questions and Answers of The order of
boiling point among
NH3 PH3 AsH3 SbH3 BiH3? are solved by group of students and teacher of NEET, which is also the largest student community of NEET. If the answer is not available please wait for a while and a community member will probably answer this soon. Hydrogen bonding is obtained when H atom is attached to electronegative N,O or F atom.
PH 3 has lower
boiling point than
NH 3. In
NH 3, intermolecular hydrogen bonding leads to molecular association. Huge amount of energy is required to break these hydrogen bonds. Hence,
NH 3 has high
boiling point. In
PH 3, no hydrogen bonding is possible. Although
PH 3 is larger than
NH 3 with greater dispersion forces,
NH 3 has a higher polar N--H bond which gives rise to H-bonding. Since the strength of the H-bond is greater than the dispersion forces, the
boiling point of
NH 3 is greater. The hydrogen bonding in
NH3 is shown below: Hence,
NH3 has a much higher
boiling point than
PH3 because. Science Chemistry Q&A Library Rank the compounds
NH3, CH4, and
PH3 in order of increasing boiling point. Rank the compounds

Explain why the
boiling point of
PH3 is lower than the
boiling point of AsH3. AsH3 is a larger molecule than
PH 3 as As is lower down the periodic table, so has a higher atomic number so more electrons. Therefore AsH 3 has more electrons than
PH 3 meaning that the instantaneous dipole produced by AsH 3 is greater. The order of
boiling points is:. 8 years ago. the basic character of hydrides decreases as follows:

The trend in
boiling points for HCl, HBr and HI is shown in your text, Figure 16.4, Pg. 749. It shows that HI has the higher
boiling point. In this case, HCl, HBr and HI all have dipoles, but LDF forces appear to be more important in determining the
boiling point than the relative dipole forces. The presence of Hydrogen bonding is negligible in these halides. >If we talk about the HF, it has strong hydrogen bonding, thus has the highest
boiling point. >Therefore, HF exists in the liquid state, and HI, HBr, and HCl exists in the gaseous state. >We can conclude, the order of
boiling point followed is HF > HI > HBr > HCl. Arrange the molecules in order of decreasing
