Question

1. Before which of the functional group tests discussed in this lab should acetone not be used to clean the test tube (Baeyer's Test, Ceric ammonium nitrate, 2,4-dinitrophenylhydrazine, Tollen's test, Litmus test).

Answer 1

I would avoid acetone before using 2,4-dinitrophenylhydrazine or Tollen's test, 2,4-dnph is a test for aldehydes and ketones while tollen's test distinguishes between aldehydes and ketones.
