Because the melting point can be very similar; also impurities change the value of the melting point.
The melting point is not enough to definitely identify the compound because different compounds may have a similar melting point range. It all depends on the compounds. If you have a compound of acetanilide and flourene, the results will lead to similar melting points of 115 degrees Celsius and 116 degrees of Celsius. The ranges will be similar so it would be hard to definitely identify the compound.
Finding the melting point of an organic compound can help with compound identification, purity assessment, and determination of its physical properties. It is commonly used in organic chemistry labs to confirm the identity of a compound and assess its quality for use in experiments or industrial applications.
One way to determine if a compound is pure is to perform a melting point test. A pure compound will have a sharp melting point, while impurities will cause the melting point to be lowered and broadened. You can also use analytical techniques such as chromatography or spectroscopy to analyze the compound's composition and identify any impurities.
One property commonly used to identify compounds in the laboratory is melting point. Each compound has a specific melting point based on its chemical structure, so comparing the observed melting point of a sample to known values can help determine its identity. Other properties such as boiling point, solubility, and spectroscopic data can also be useful for compound identification.
To determine the melting point of a compound, one can use a melting point apparatus. The compound is heated gradually until it changes from a solid to a liquid state. The temperature at which this change occurs is recorded as the melting point of the compound.
A single melting point determination may not be enough to accurately identify a solid compound because different compounds can have similar or identical melting points. Additional tests such as infrared spectroscopy, mass spectrometry, or elemental analysis are needed to confirm the identity of a compound.
Melting and boiling points are different for each compound or element.
I do not believe that any chemist would choose to identify a compound by using only the melting point; why create such difficulties for yourself?

For example the melting point.
Melting point and boiling point determination can help in identifying unknown compounds by comparing the experimental values with known values in databases. A match can indicate the compound's identity. Additionally, the range of melting point and boiling point can provide information on the purity and molecular structure of the compound.
Finding the melting point of an organic compound can help with compound identification, purity assessment, and determination of its physical properties. It is commonly used in organic chemistry labs to confirm the identity of a compound and assess its quality for use in experiments or industrial applications.
Three physical properties used to identify compounds are melting point, boiling point, and density. These properties can be compared to known values of compounds to determine the identity of an unknown compound.
One way to determine if a compound is pure is to perform a melting point test. A pure compound will have a sharp melting point, while impurities will cause the melting point to be lowered and broadened. You can also use analytical techniques such as chromatography or spectroscopy to analyze the compound's composition and identify any impurities.
Pure substances have very specific melting (and boiling) points. Assuming the substance is pure you could measure the melting point and compare it to a known database of melting points.
Since each compound has a specific melting point, knowing the melting point can narrow down the possibilities so that only a few additional tests are needed to identify the compound.
