acetic anhydride lewis structure
How do you identify acetic anhydride?
Acetic anhydride appears as a clear colorless liquid with a strong odor of vinegar.
Flash point 129 °F.
Corrosive to metals and tissue.
Density 9.0 lb /gal.Acetic Anhydride is a colorless liquid with a characteristic sharp odor.
It is used in making plastics, drugs, dyes, perfumes, explosives and aspirin.
What is the structure of the acetic anhydride?
The acetic anhydride structure consists of two acetyl groups joined by an oxygen atom in the center.
The acetyl group (CH3CO) is composed of a methyl group (CH3) and a carbonyl group (CO).
The arrangement of these atoms determines its chemical properties and functions.
R and R' represent alkane groups.
