Question

An organic compound a is used as a preservative in pickles and has a molecular formula c2h4o2. This compound reacts with ethanol to form a sweet smelling compound



b. Determine compound



a. Write chemical equation for this rxn. How can vinegar be obtained from compound

Answer 1

HELLO THERE!

The concept involved in this question is that, Esters are produced when carboxylic acid is treated with alcohol in presence of concentrated sulphuric acid. Esters are sweet smelling (actually the smell is called as fruity smell).

So, the organic compound mentioned here must be a carboxylic acid, and by the formula, we understand that it is Ethanoic acid because the formula (general) contains two carbons.

So, the compound is Acetic acid/Ethanoic acid: CH₃COOH.

Chemical equation:

=> C₂H₅OH + CH₃COOH ------> CH₃COOC₂H₅ + H₂O

The ester (sweet smelling compound that is talked about) formed is Ethyl Acetate, or Ethyl Ethanoate.

THANKS!
