using the procedures, we used dichloromethane as the unknown
mixture and i was able to extract benzoic acid for an acid,
5-chloro-2-methoxyanaline for a base compound and biphenyl for
neutral compound.
i don't know if that answers the missing part but if it didn't
could you be specific please? thank you!

Based on the Wittig Reaction exp. below, please answer a) and
b). In b) you can disregard the part about the IR, just please
interpret and assign protons, shift values, which protons are for
which groups, etc on the HNMR. The % yield was 34%, and MP was
lower than expected (to assist with answering part a). This should
be all the information you need to answer the question.

Tollens\' reagent, [Ag(NH3)2] , is used to test for the presence
of aldehydes. The reaction results in reduction of the silver ion
to form a mirror of silver metal. Concurrently, the aldehyde is
oxidized. Draw the structure of the organic product resulting from
treatment of 3-methylbutanal with Tollens\' reagent, followed by
treatment with acid.
