Identification of Solid Unknown 18 S
Identification of Solid Unknown 18 S
Solubility Test Results:
Because unknown 18 S was soluble in NaOH but not in NaHCO3, it could be determined that the unknown compound was a phenol. Classification tests were performed to ensure the compound was a phenol.
Classification Test Results:
The classification tests performed confirmed that Unknown 18 S was a phenol. Both tests for the phenol functional group yielded a positive result.
Possible Compounds:
Derivative:
4-nitrophenol α-Naphthylurethane derivative
Observed MP 149.6ºC
Literature MP 150ºC
Through a series of solubility and classification tests, and by generating and finding the melting point of the derivative, Unknown #18 S was determined to be 4-nitrophenol.
