Formation fo ethyl acetate, acid-catalyzed
Hello, In a 125-mL Erlenmeyer flask, 10-mL ethanol, 12 mL glacial acetic acid, and 15 drops of concentrated sulfuric acid (18 M), are added together with a boiling stone. Ethyl acetate is distilled.
1 Write the equation for the formation of ethyl acetate
2 What is the purpose of sulfuric acid?
3 What happens if water is removed from the reaction mixture.
4 Write the structure of the product formed when ethanol is oxidized by sodium dichromate
