Question

Summarize how each of the techniques below will allow you to identify an unknown compound by mentioning the information obtained from each technique.
1 solubility determination
2 MP determination
3 TLC
4 Recrystalization

Answer 1

I am not sure about the recrystallization technique since it was not studied in my lecture.

Answer 2

Its basically used to purify a compound on the basis of solubility.
for instance you have some compound you extracted from some place or whatver, you first dissolve it in a solvent, the solution is filtered to remove the insoluble impurities, and the solvent is then evaporated to produce the solid compound and get a more "pure" organic compound.

I think this is works for only organic compounds, but I'm actually not sure if it works for inorganics like organometallics species of the like.

Answer 3

After you obtain the more pure species, you can subject it to a series of tests to identify what you have, for instance, boiling point, melting point, NMR, IR, proton NMR, etc.,
