Why is it misleading to identify a solid compound just from a lone melting determination?

Because the melting point can be very similar; also impurities change the value of the melting point.

How can a mixed melting point confirm the identity of an unknown compound?
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.
When are oil baths and water baths used respectively for melting point determination?
oil is used when we are determining the melting point of compound higher than 100 while for those compound which have melting point less then 100 we use water bath
How do the melting and boiling point determine the purity of the substance and identify them?
*usually* melting point is a good indicator of a substance's purity. The technique of melting point determination is used frequently in organic chemistry labs.
What are the applications of finding the melting point of an organic compound?
To check the purity of the organic compound.
What information can be obtained from the melting point of a compound as an industrial chemist?
purity of a compound
How do you identify solids at melting or boiling points?
Melting and boiling points are different for each compound or element.
How could you positively identify a compound using only melting point determinations?
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?

What are the useful physical property used to identify an organic compound?
For example the melting point.
What are three physical properties used to identify compound?
melting point density and color
When are oil baths and water baths used respectively for melting point determination?
oil is used when we are determining the melting point of compound higher than 100 while for those compound which have melting point less then 100 we use water bath
How can melting point and boiling point determination be used in identifying and or characterizing unknown compounds?
compounds are identified because each compound have characteristically different melting and boiling points.
How do the melting and boiling point determine the purity of the substance and identify them?
*usually* melting point is a good indicator of a substance's purity. The technique of melting point determination is used frequently in organic chemistry labs.
How could the identify of a compound be established by melting point?
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.
How is the meltin point of a pure solid used in identifying it?
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.
Is an alloy of aluminum has a melting range instead of a melting point is the alloy a compound?
It is a compound. All pure elements have a certain exact melting point.
How is the melting of an impure compound expected to change with recrystallization?
The melting point of an impure compound will become closer to that of the actual melting point of the pure substance with recrystallization of your mixture.
