The melting point of benzoic acid is 122.38 °C or 252 °F or 396 K.
Because benzene is a cycloalkene. The intermolecular forces are pretty strong to break in cyclic structures

Who will melt earlier benzoic acid or sodium chloride?
Sodium chloride will melt earlier than benzoic acid. Sodium chloride has a lower melting point of 801 degrees Celsius, while benzoic acid has a melting point of 122 degrees Celsius.
What is the melting point of fifty percent 2-naphthol and fifty percent benzoic acid?
The melting point of a mixture of 50% 2-naphthol and 50% benzoic acid will depend on the exact proportion of each compound present and any potential interactions between them. However, the melting points of the individual compounds are approximately 122°C for 2-naphthol and 122-123°C for benzoic acid.
What is the eutectic temperature for benzoic and mandelic acid?
The eutectic temperature for the benzoic and mandelic acid system is approximately 119°C. At this temperature, both compounds will fully dissolve in each other to form a eutectic mixture, exhibiting the lowest melting point in the system.
What would happen to the melting point of pure benzoic acid if 2-naphthol was mixed in?
The melting point of pure benzoic acid would likely decrease if 2-naphthol was mixed in. This is because the presence of 2-naphthol can disrupt the crystal lattice structure of benzoic acid, making it easier for the molecules to move past each other and causing the melting point to decrease.
What happens to Benzoic acid on heating?
Benzoic acid sublimes and transforms directly from a solid to a gas when heated without melting. This process is driven by the compound's low vapor pressure and is commonly used for purification purposes.
Who will melt earlier benzoic acid or sodium chloride?
Sodium chloride will melt earlier than benzoic acid. Sodium chloride has a lower melting point of 801 degrees Celsius, while benzoic acid has a melting point of 122 degrees Celsius.
Why does benzoic acid has high melting point?
Benzoic acid has a high melting point because it forms strong intermolecular hydrogen bonds between its molecules. These bonds require a lot of energy to break, resulting in a high melting point. Additionally, benzoic acid molecules are relatively large and exhibit a high degree of symmetry, contributing to its strong intermolecular forces.
Why benzoic acid unmelt even 200 Celsius?
Benzoic acid has a high melting point of 122.4 degrees Celsius, which explains why it remains solid even at 200 degrees Celsius. The strong intermolecular forces, such as hydrogen bonding, present in benzoic acid molecules require a significant amount of energy to overcome, hence it retains its solid state at temperatures below its melting point.
What acids have a melting point of 69 degree?
One example of an acid with a melting point around 69 degrees Celsius is benzoic acid. It has a melting point of 122-123 degrees Fahrenheit, which is approximately 50-51 degrees Celsius.
What are physical properties of benzoic acid?
Physical properties of benzoic acid:-density: 1,2659 g/cm3-melting point: 122,41 oC-boiling point: 249,2 oC-refractive index: 1,5397

What the composition of a melting point mixture?
A melting point mixture typically consists of a 1:1 ratio of the compound being tested and a known standard compound, such as benzoic acid. The mixture is heated slowly to determine the melting point range of the unknown compound. By comparing the melting point range of the unknown compound to that of the standard, the identity or purity of the unknown compound can be determined.
What is acetic acid melting point?
The acetic acid melting point is approx. 17 oC.
Given a pure sample that is either pure benzoic acid or 2-naphthol give a procedure that can be used to determine the identity of the sample?
One possible procedure is to measure the melting point of the sample. Benzoic acid has a higher melting point (122-123°C) compared to 2-naphthol (120-123°C). By comparing the observed melting point with the reported values, the identity of the sample can be determined. Additionally, performing a solubility test can differentiate these compounds, as benzoic acid is soluble in hot water while 2-naphthol is not.
What happens to Benzoic acid on heating?
Benzoic acid sublimes and transforms directly from a solid to a gas when heated without melting. This process is driven by the compound's low vapor pressure and is commonly used for purification purposes.
