If you were given an unknown substance that was either an ester or carboxylic acid, what tests could you use to identify the type of molecule you were given?
Homework Answers
When carboxylic acids are treated with solid NaHCO3, CO2. gas is evolved or a brisk effervesence is obtained indicating the presence of carboxylic acid.
whereas no such observation is observed in case of esters.

There's a sample of a carboxylic acid that could be mixed with an ester (they are isomers). Both compounds have the same molecular formula, C3H6O2. Explain how you could use mass spectrometry to find if the sample is a mixture of isomers or pure carboxylic acid. Draw Lewis structures of the two compounds.

An acid anhydride reacts with an alcohol to form one
ester and one carboxylic acid. An unsymmetrical acid anhydride can
react with alcohol at either carbonyl carbon, so there are two
possible esters and two possible carboxylic acids.

I know the reactivity of carboxylic acid is acid halide > anhydride> ester > amide. "Recall that benzoyl chloride was slow to react with water, does this fit with the trend you just described? Why or why not?" So I think the answer to this statement should be it doesn't fit the trend. But could someone explain why?
