Find how scientists prepare acid anhydrides and what happens when they react with water. Draw both reactions using an example of maleic anhydride (which is the dienophile used in the lab experiment)
Homework Answers
Maleic anhydride can be synthesized by dehydration of maleic acid.
while the hydrolysis of anhydride with water at 60°C forms maleic acid which is a kinetic product and at higher temperature maleic acid is converted to fumaric acid which is a thermodynamic product.

When acyl halides (R?COX) or acid anhydrides (R?OC?O?CO?R) react
with primary amines (R?NH2) or secondary amines (R2NH), the
reaction yields an amide:
O || R?C?NR2
where R may be an alkyl group or hydrogen atom.
For example, propanoyl chloride
( O ||CH3CH2C?Cl)
reacts with ethanamine (CH3CH2NH2) to form
(O || CH3CH2C?NHCH2CH3).
The IUPAC name for the product isN-ethyl propanamide, as
it is formed from ethanamine and propanoyl
chloride.
