I'm asking about Carboxylic acid and its Derivatives. We were ask to research in advance prior to our expt.

1.Dissolve a pinch of benzoic acid in 2ml hot water. heat if necessary. Add 10% NH4OH till slightly basic to litmus. Boil of excess ammonia. ADD 2 DROPS OF FERRIC CHLORIDE SOLUTION.color?equation?

-what happens to this reaction?what does ferric chloride test do? equation?

2. Heat about 0.1g oxalic acid in a test tube with a delivery tube, the other end dipping into lime water. what gas evolved?equation?what is formed in the lime water?equation?

3. Repeat #2 using succinic acid.

-this test is named decarboxylation of dicarboxylic acid, how does this reaction work?what is the gas evolved?what is the equations?what is formed in the lime water?

Answer:
1. Reacting Benzoic acid and ammonium hydroxide yields ammonium benzoate. Ferric Chloride (FeCl3) forms a complex with a lone pair of electrons from the carboxylate salt. The compound turns purple when this complex is formed.
