What is the boiling point of benzene?
What is the boiling point of benzene?

Benzene/Boiling point
What is the boiling point of benzene at 1 atm?
80.1 °C
For benzene (C6H6), the normal boiling point is 80.1 °C and the enthalpy of vaporization is 30.8 kJ/mol.
What is the boiling point of 100% benzene?
Note! Benzene boiling point at atmospheric pressure is 80 °C (176°F), and hence, benzene must be pressurized to remain liquid at higher temperatures than that.
What is the melting and boiling point of benzene?
Benzene has a boiling point of 80.1 °C (176.2 °F) and a melting point of 5.5 °C (41.9 °F), and it is freely soluble in organic solvents, but only slightly soluble in water.
Why benzene has low boiling point?
Benzene has a lower boiling point than toluene because it is more symmetrical. Benzene has a higher melting point than toluene because it has weaker intermolecular forces. Benzene and toluene are similar in intermolecular attraction; they both…
Does benzene have a high boiling point?
Benzene/Boiling point
Boiling points Benzene boils at 80°C, which is higher than other hydrocarbons of similar molecular size (pentane and hexane, for example). The higher boiling point is presumably due to the ease with which temporary dipoles can be set up involving the delocalized electrons.
How do you find the boiling point of benzene?
The boiling temperature of benzene when the atmospheric pressure is 500 torr is 340.93 K
- = initial pressure which is the pressure at normal boiling point = 1 atm = 760 torr.
- = final pressure = 500 torr.
- = Heat of vaporization = 33.9 kJ/mol = 33900 J/mol (Conversion factor: 1 kJ = 1000 J)
What is the CP of benzene?
Chemical, physical and thermal properties of benzene, also called benzol. Phase diagram included.
| Property | Value | Unit |
|---|---|---|
| Heat (enthalpy) of evaporation | 33.8 | kJ/mol |
| Specific heat capacity, Cp (gas) | 82.4 | J/mol K |
| Specific heat capacity, Cp (liquid) | 133 | J/mol K |
| Specific heat capacity, Cp (solid) at 32°F/0°C | 118 | J/mol K |
Does benzene have a low boiling point?
Boiling points Benzene boils at 80°C, which is higher than other hydrocarbons of similar molecular size (pentane and hexane, for example). The higher boiling point is presumably due to the ease with which temporary dipoles can be set up involving the delocalized electrons.
What is the melting point of benzene?

Which benzene has highest boiling point?
For the same aryl group, b.p. increases as the size of the halogen increases. Thus, C6H5I has the highest b.p.
What is molecular formula of benzene?
C6H6
Benzene/Formula
Benzene is an important organic chemical compound with the chemical formula C6H6 and its molecule is composed of 6 carbon atoms joined in a ring with 1 hydrogen atom attached to each carbon atom.
What is the boiling point of benzene at atmospheric pressure?
Benzene boiling point at atmospheric pressure is 80 °C (176°F), and hence, benzene must be pressurized to remain liquid at higher temperatures than that. The output density is given as kg/m 3, lb/ft 3, lb/gal (US liq) and sl/ft 3 .
What happens to benzene when heated and cooled?
However, if heated it becomes a gas, and when cooled it becomes a solid. The phase diagram for benzene shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the benzene boiling point with changes in pressure.
What are the boiling points of benzene ethylene chloride and n-heptane?
1 Title Boiling points of benzene, ethylene chloride, n-heptane, and 2,2,4-trimethylpentane over the range 660- to 860-mm pressure Author Smith, E.R.; Matheson, H.
What is the specific weight of benzene?
Benzene – Density and Specific Weight. Specific weight, γ, has units typically [N/m 3] or [lb f /ft 3 ] is defined by the ratio of the weight to the volume of a substance: γ = (m * g)/V = ρ * g [2] where g = acceleration due to gravity, units typically [m/s 2] and value on Earth usually given as 9.80665 [m/s 2]…
