Which of the following solvents has maximum distribution coefficient at 200°C for the extraction of acetic acid from acetic acid – water system?
Show Hint
When selecting solvents for extraction, the distribution coefficient is a key factor. Solvents with higher coefficients are generally more effective in extracting solutes.

The Correct Option is B
Solution and Explanation
Step 1: Understanding the distribution coefficient.
The distribution coefficient (or partition coefficient) of a solvent is a measure of its relative ability to extract a solute from one phase (usually water) into another phase (such as an organic solvent). The higher the distribution coefficient, the more effective the solvent is for extraction. For acetic acid extraction, the distribution coefficient is typically higher for solvents like ethyl acetate compared to others.
Step 2: Conclusion.
Ethyl acetate is known to have the maximum distribution coefficient at 200°C for the extraction of acetic acid from an acetic acid-water system. Therefore, the correct answer is (2).
