Does NaCl have higher boiling point than HCl?
The intermolecular force is greater in the ionic compounds, followed by a covalent bond. Sodium chloride is an ionic compound, while hydrochloric acid is a covalent compound. The boiling point of NaCl is 1465∘C 1465 ∘ C and HCl is −85.05∘C − 85.05 ∘ C . Hence, NaCl has a higher boiling point.
Does NaCl or HCl have a higher melting point?
NaCl is an ionic compound so it has ion-ion attractions and dispersion forces. HCl has dispersion forces and dipole-dipole interactions between the molecules. Ion-ion attractions are stronger than dipole-dipole interactions so NaCl has a higher melting point.
Does NaCl have a high boiling point?
2,669°F (1,465°C)Sodium chloride / Boiling point
Does HCl have a higher boiling point?
The higher normal boiling point of HCl (188 K) compared to F2 (85 K) is a reflection of the greater strength of dipole-dipole attractions between HCl molecules, compared to the attractions between nonpolar F2 molecules.
Why HCl has low boiling point?
HCl has the least boiling point due to the small dispersion intermolecular forces.
Which has a higher boiling point?
In general, larger molecules have higher boiling points than smaller molecules of the same kind, indicating that dispersion forces increase with mass, number of electrons, number of atoms or some combination thereof.
Why does HCl have lower boiling point than NaCl?
HCl has a simple molecular structure. There are weak intermolecular forces between the molecules. These intermolecular forces need to be broken to melt HCl, this requires a small amount of energy and therefore HCl has a relatively low melting point.
Why does HCl have a low boiling point?
The boiling point depends on the intermolecular forces of attraction. HCl has weaker ‘Van der Waals’ forces (London dispersion forces in this case) as compared to HBr due to less number of electrons, which results in lower boiling point.
Why does HCl have a lower boiling point than NaCl?
Does HCl have a high melting point?
-173.6°F (-114.2°C)Hydrogen chloride / Melting point
Hydrogen chloride (HCl) has a melting point of -114.2 °C. Sodium chloride (NaCl) has a melting point of 801 °C.
Which has higher boiling point HF or HCl?
a) The intermolecular bonding for HF is van der Waals, whereas for HCL, the intermolecular bonding is hydrogen. Since the van der Waals bond is stronger than hydrogen, HF will have a higher boiling temperature.
Which has the highest boiling point HF or HCl?
Hydrogen bonding is the strongest intermolecular force. Due to strong intermolecular forces, the molecules of HF will be tightly packed in a lattice. Thus, HF will have the highest boiling point since the boiling point of a system depends upon the intermolecular interactions. Which of the following has highest boiling point HF HCL?
Which intermolecular force has the highest boiling point?
Propionamide has the strongest intermolecular forces, It should have the highest boiling point. What determines a boiling point? The boiling point of a liquid is reached when the total vapor pressure of the liquid is equivalent to the atmospheric pressure. The temperature at which this occurs is called the boiling point.
What is the difference between HF and HCl?
b) The intermolecular bonding for HF is covalent, whereas for HCL, the intermolecular bonding is hydrogen. Since the covalent bond is stronger than van der Waals, HF will have a higher boiling temperature.
Why do large molecules have higher boiling points than smaller molecules?
Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules. It is very important to apply this rule only to like compounds.
