Question

An organic compound 'A' is widely used as a preservative in pickles and has molecular formula C2H4O2. This compound reacts with ethanol to form a sweet smelling compound'B'
1) identify the compound 'A'
2)Write the chemical equation for its reaction with ethanol to form compound 'B'
3)How can you get compound 'A' back from 'B'
4)Name the process and write the chemical equation for conversion of 'B' to 'A'

Answer 1

1- A is ethanoic acid or acetic acid or vinegar (CH3COOH).
2-CH3COOH+C2H5OH---------->C4H8O2 ethyl ethanoate + water
3-On hydrolysis with dil. alkali NaOH give back A but in it's constituent salt.
4- Hydrolysis of ester
C4H8O2 + dil. NaOH -------*>CH3COONa +C2H5OH

Answer 2

1- A is ethanoic acid or acetic acid or vinegar (CH3COOH).

2-CH3COOH+C2H5OH---------->C4H8O2 ethyl ethanoate + water

3-On hydrolysis with dil. alkali NaOH give back A but in it's constituent salt.

4- Hydrolysis of ester

C4H8O2 + dil. NaOH -------*>CH3COONa +C2H5OH
