All acid groups are polar to greater or lesser degree, irrespective of what they are attached to.
Cinnamic acid is a competitive inhibitor. It competes with the substrate for binding to the enzyme's active site.
The addition of bromine to trans-cinnamic acid occurs more slowly than to a normal alkene due to the steric hindrance caused by the phenyl group in cinnamic acid, which restricts the approach of the bromine molecule. The resonance stabilization of the double bond in cinnamic acid also hinders the electrophilic attack of bromine, making the reaction slower compared to a normal alkene with no such effects.
In the bromination of trans cinnamic acid, a reaction called electrophilic aromatic substitution takes place. This involves the addition of a bromine atom to the benzene ring of the cinnamic acid molecule. The bromine atom acts as an electrophile, meaning it is attracted to the electron-rich benzene ring. This reaction is typically carried out in the presence of a catalyst, such as a Lewis acid, to facilitate the addition of the bromine atom to the benzene ring.
Fumaric acid is polar. It contains carboxylic acid functional groups which make it polar due to the presence of electronegative oxygen atoms.

Cinnamic acid is a competitive inhibitor. It competes with the substrate for binding to the enzyme's active site.
Isopropyl cinnamate is the ester produced when isopropyl alcohol is reacted with cinnamic acid. This reaction typically involves an acid-catalyzed esterification process.
When ethanol reacts with cinnamic acid in the presence of a catalyst, it forms ethyl cinnamate, which is a commonly used flavoring and fragrance compound. It has a sweet, fruity odor similar to that of strawberries.
The addition of bromine to trans-cinnamic acid occurs more slowly than to a normal alkene due to the steric hindrance caused by the phenyl group in cinnamic acid, which restricts the approach of the bromine molecule. The resonance stabilization of the double bond in cinnamic acid also hinders the electrophilic attack of bromine, making the reaction slower compared to a normal alkene with no such effects.
When urea and cinnamic acid are mixed together, the melting point of the mixture is typically lower than the melting point of the individual components. This is because the interaction between urea and cinnamic acid disrupts the crystal lattice structure, making it easier for the mixture to melt at a lower temperature.
To convert benzaldehyde to cinnamic acid, you can use the Perkin reaction. In this reaction, benzaldehyde is treated with acetic anhydride in the presence of a basic catalyst like sodium acetate to form cinnamic acid. The reaction proceeds through an aldol condensation followed by a dehydration step to give the final product.
