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 melting point of 122oC. If your sample did not melt even at 200oC, then you can only assume that the sample in Whole or Part was not Benzoic Acid. It must have been contaminated with some other compound with a much higher melting point.
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 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.
How the two terms freezing point and melting point relate to one another?
These terms are synonyms.
What is the melting point of benzoic acid?
the melting/ freezing point is approximately 50°C
Why does benzoic acid has high melting point?

Additionally, benzoic acid molecules are relatively large and exhibit a high degree of symmetry, contributing to its strong intermolecular forces.
Who will melt earlier benzoic acid or sodium chloride?
sodium chloride melt earlier because it has low freezing point
Why benzoic acid unmelt even 200 Celsius?

What would happen to the melting point of pure benzoic acid if 2-naphthol was mixed in?
The literature value of the melting point of pure benzoic acid is about 122.4 degrees Celsius, while the literature value of the melting point of pure 2-naphthol is close at 122 degrees Celsius. Nevertheless, the melting point of the benzoic acid should be depressed (go down) compared to the literature value if you were to add 2-naphthol because the sample you were testing would then be impure, even if that impurity does have a similar melting point. Also, the range over which the sample melts should get larger as well. Instead of melting within a degree or less, it may melt over the course of several degrees. So I just tested this in lab, and I can't promise that this is 50/50, but my melting point for 2-naphthol with Benzoic acid is 104.1-106.0 degrees Celsius This is a very basic answer, and the trend is true. However, with my organic chemistry professor, this answer would be followed by a blank look and "Why?" The best way to think of this is to look at the chemical structure of Benzoic Acid and 2-naphthol separate. Go ahead and Google it on a new tab. Now look at the molecule of the two together. And think: "What does the composite molecule have that the two alone don't?" Give up? Electronegativity. The more electronegative a molecule is the greater its reactivity. As in the compound molecule will melt easier than the two 'pure' substances.

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.
How the two terms freezing point and melting point relate to one another?
These terms are synonyms.
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.
Does silicon have a high melting point?
Yes, it has a melting point of 1683 Kelvin.
How do freezing point and melting point relate?
The freezing point and melting point of a substance are the same temperature, known as the equilibrium melting point, at which the solid and liquid phases coexist in equilibrium. When a substance is cooling down, it will reach its freezing point temperature, causing it to solidify. Conversely, when a substance is heating up, it will reach its melting point temperature, causing it to liquefy.
