Name                                                Date               

 

Unkn. No.          Identity of Compound                                 

This was Font/Pitch 1,10 - Off. This was Font/Pitch 4,10 - On. This was Font/Pitch 4,10 - Off. This was Font/Pitch 1,10 - On.

1.         Physical properties of purified material:

 

            physical state                                 color             

 

            b.p.                    This was Font/Pitch 1,10 - Off.     m.p.                  

 

            refractive index (liq. only)                   other            

 

2.         Preliminary Classification

            a)  Solubility tests (write "s" if soluble; "i" if insoluble).

 

            H2O       Et2O        HCl        NaOH        NaHCO3        H2SO4      

 

            Classification                                                     

            b)            Indicator tests (note the color change, if any)

 

                        A-I                           A-II                          

 

                        B-I                           B-II                          

 

            Classification:                                                   

 

3.            Functional Group Tests

 

 On a separate sheet of paper, prepare a table with the column headings:  This was Font/Pitch 1,10 - Off. Reagent, Result, and Inference.  In the appropriate spaces, list the actual reagent and observed result of every functional group test applied to the unknown, and the inference drawn in each case.  (See sample below.)

 

Reagent Result Inference
2,4-DNPH orange ppt; red color with alc. KOH carbonyl group
Tollens no silver mirror or ppt ketone (no aldehyde)
NH2OH, KOH no purple color no ester group

 

4.         Probable Compounds:  List all compounds with m.p. or b.p. within 5o of that of the unknown, which could be identical to the unknown.  Also list the useful derivatives and their m.p.'s.

 

5.         Derivatives made:  List the derivatives of the unknown that were actually prepared and their observed m.p.'s.

6.         Spectroscopic Data:  Tabulate ir and nmr data, if obtained.
