Identifyin unknown compounds

[elliegurl297]

I have my ch6 practical coursework coming up and we have to identify 6 compounds and theirs 8 all together that they could be.
what test can i use to show I have diphenylmethanone, benzonitrile, ethyl benzenecarboxylate (aromatic ester) and ethanamide?

I've been trying to think what i could do now for past week and I just keep going round in circles. There is limited resources I can use too :
dilute sodium hydoxide
dilute sulfuric acid
sodium hydrogencarbonate
litmus paper
sodium nitrite
tollens and iodoform
methanol

I know that the ester is insolule in water so i would try to dissolve it in methanol.

Any ideas would be greatly appreciated
thankyou

!Diphenylmethanone: To identify diphenylmethanone, you can perform a Molisch test. Add a few drops of concentrated sulfuric acid to a sample of the compound and place a drop of a-naphthol solution on top of the mixture. If a violet ring appears at the interface, then the compound is likely diphenylmethanone. Benzonitrile: To identify benzonitrile, you can perform a nitrile test. Add a few drops of dilute sodium hydroxide to a sample of the compound and if a white precipitate forms, then the compound is likely benzonitrile. Ethyl Benzenecarboxylate (Aromatic Ester): To identify an aromatic ester, you can perform an esterification test. Add a few drops of dilute sulfuric acid to a sample of the compound and warm the mixture gently. If an odor of ethyl alcohol is detected, then the compound is likely an aromatic ester. Ethanamide: To identify ethanamide, you can perform a carbylamine test. Add a few drops of dilute sodium hydrogencarbonate to a sample of the compound, followed by a few drops of dilute sodium nitrite. Then add a few drops of chloroform and shake the mixture vigorously. If an ammonia smell is detected, then the compound is likely ethanamide.
