Chemical Reaction of organic chemistry Question see below

Question

A Chemist reacts two unknown substances A and B. She then separates the products of this reaction into two equal amounts, in container X and in container Y. The container X, a strong oxidizing agent is added, once that reaction is complete, she adds another strong oxidizing agent to that product. The resulting products of the second oxidation will react with a base to form a salt and water. When the new product container X in is mixed with container Y and sulfuric acid is added, an ester is formed. What are the identities(provide organic family and name) of A,B,X and Y

Answer 1

I will take a stab at this.

If A and B are an alkene and water respectively, with a catalyst they will react to form an alcohol.

The alcohol in X can be successively oxidized to an aldehyde and then to a carboxylic acid.

The carboxylic acid in X will react with base to form a salt. Container Y still contains an alcohol.

When the carboxylic acid in X is reacted with the alcohol in Y, an ester is formed.
