A Fischer esterification is performed in which acetic acid is placed in a test tube along with ethanol and concentrated sulfuric acid. After the test tube was warmed for twenty minutes, it was noticed that the reaction mixture contained two layers. Identify the contents of each layer in the test tube by dragging and dropping the labels into the appropriate box. A. Top Layer

B. Bottom layer

1. Alcohol

2. Aqueous layer

3. sulfuric acid

4. carboxylic acid

5. ester
