Why does phosphorus trichloride have a high melting point?
PCl3 is a polar molecule and its strongest intermolecular forces are dipole-dipole interactions. It has the next highest melting point. The metal cation in MgCl2 has a greater charge than the cation of NaCl and will have a higher melting point.
Does PF3 have a high melting point?
-240.7°F (-151.5°C)
Phosphorus trifluoride/Melting point
What intermolecular forces does phosphorus trifluoride PF3?
PF3 is a covalent bond. After it forms three single bonds, the P will have one lone pair that will force the attraction between the two bonded pairs. A molecule’s strongest bond can be by covalent or ionic bonds.
Which one has a higher boiling point MgCl2 or PCl3?
Bonding forces are stronger than nonbonding (intermolecular) forces. (a) Mg2+ and Cl− are held together by ionic bonds while PCl3 is covalently bonded and the molecules are held together by dipole-dipole interactions. Ionic bonds are stronger than dipole interactions and so MgCl2 has the higher boiling point.
Why does nacl have a higher boiling point than PCl3?
Explanation: Sodium chloride is a non-molecular material, that consists of an infinite array of positive and negative ions that are held together by STRONG electrostatic forces. And PCl3 is a discrete MOLECULAR material, which has a normal boiling point of 76.1 ∘C .
Does phosphorus trichloride have a high boiling point?
169°F (76.1°C)

Is phosphorus trifluoride a covalent bond?
PF3 P F 3 is a covalent compound as it is formed by the sharing of electrons between phosphorus and fluorine atoms. Each fluorine atom share one electron with phosphorus and the octet of each atom gets completely filled.
What is the boiling point of PCl3?
Is mgcl2 higher boiling point?
Magnesium chloride (MgCl2) As with sodium chloride, large amounts of heat energy are needed to overcome the attractions between the ions (because of the high lattice enthalpy of the compound), so the melting and boiling points are also high.
What is the boiling point of pcl3?
Why the melting point of sodium chloride is much higher than that of phosphorus trichloride?
The result? An infinite array of charged ions within an electrostatic lattice. This non-molecularity gives rise to hardness and rigidity, and exceedingly high melting points, as well as non-conductivity in the solid state. Contrast this with phosphorus trichloride.
Why does PCl3 have a low boiling point?
PCl3 is a covalent molecule and the bonds between such molecules are secondary in nature and hence not a lot of energy is required to break these bonds. This accounts for the low boiling point.
What does PCl3 stand for?
phosphorus chloride (PCl3) phosphorus chloride, (32)P-labelled. phosphorus trichloride. trichlorophosphine
What is the boiling point of PF3?
P F 3 is a room temperature gas with a normal boiling point of − 101.8 ° C; on the other hand, P C l 3 is a room temperature LIQUID with a normal boiling point of 76.1 ° C.
What is the difference between PCl3 and MgCl2?
PCl3 is a covalent molecule and the bonds between such molecules are secondary in nature and hence not a lot of energy is required to break these bonds. This accounts for the low boiling point. MgCl2, on the other hand, being an ionic compound, is found in a 3-D, continuous, non-directional lattice.
