An equimolar mixture of benzoic acid and benzyl alcohol is dissolved in equal volumes of ether and 5% aqueous NaOH. The resulting mixture separates into two immiscible liquid layers. Which of the following is approximately correct?
  • a)
    Both organic solutes are largely in the ether layer
  • b)
    The benzyl alcohol is in the ether layer and the benzoic acid is in the water layer
  • c)
    Both organic solutes are largely in the water layer
  • d)
    The benzyl alcohol is in the water layer and benzoic acid is in the ether layer
Correct answer is option 'B'. Can you explain this answer?

Explanation:

Given:
- Equimolar mixture of benzoic acid and benzyl alcohol
- Dissolved in equal volumes of ether and 5% aqueous NaOH
- Resulting mixture separates into two immiscible liquid layers

Explanation:
When a mixture of benzoic acid and benzyl alcohol is dissolved in equal volumes of ether and 5% aqueous NaOH, the mixture separates into two immiscible liquid layers due to the difference in solubility of the components in the two phases.

Key Points:
- Benzoic acid is a carboxylic acid and is more soluble in the aqueous phase due to its ability to form hydrogen bonds with water.
- Benzyl alcohol is an alcohol and is more soluble in the organic phase (ether) due to its nonpolar nature.
- Sodium hydroxide (NaOH) is a strong base and can deprotonate the carboxylic acid group of benzoic acid to form sodium benzoate, which is more soluble in the aqueous phase.

Explanation of Options:
a) Both organic solutes are largely in the ether layer: This option is incorrect because benzoic acid, being a carboxylic acid, is more soluble in the aqueous phase.
c) Both organic solutes are largely in the water layer: This option is incorrect because benzyl alcohol, being an alcohol, is more soluble in the organic phase.
d) The benzyl alcohol is in the water layer and benzoic acid is in the ether layer: This option is incorrect because benzoic acid is more soluble in the aqueous phase.

Correct Option:
b) The benzyl alcohol is in the ether layer and the benzoic acid is in the water layer: This option is correct. Benzyl alcohol, being an alcohol, is more soluble in the organic phase (ether). Benzoic acid, being a carboxylic acid, is more soluble in the aqueous phase. Therefore, benzyl alcohol will be present in the ether layer and benzoic acid will be present in the water layer.

Benzyl alcohol is not neutralised by NaOH, whereas benzoic acid forms salt C6H5COONa and goes into aqueous layer.
