An organic compound is boiled with alcoholic potash. The product is cooled and acidified with HCl. A white solid separates out. The starting compound may be
- A ethyl acetate
- B methyl acetate
- C ethyl benzoate
- D ethyl formate
Answer & Solution
Correct Answer
(C) ethyl benzoate
Step-by-step Solution
Detailed explanation
Ethyl benzoate is boiled with alc. potash to give ethyl alcohol and potassium benzoate. Potassium benzoate is converted into benzoic acid, a white solid which separates out.…
