What reagent is used to hydrolyse ethyl benzoate?
Sodium hydroxide.
What conditions are used?
Heat under reflux for 30 minutes.
What products form?
Sodium benzoate and ethanol.
What is done after hydrolysis?
Cool the mixture to room temperature and add hydrochloric acid.
What happens when HCl is added?
A precipitate of benzoic acid forms.
How is the benzoic acid separated?
Using suction filtration.
Why is sodium benzoate soluble in water?
It is ionic.
Why is benzoic acid insoluble in water?
Although the COOH group is polar and can hydrogen bond, the benzene ring is non-polar.
What determines solubility in water for an organic compound?
Whether the polar or non-polar part has the greater influence.
