All acid groups are polar to greater or lesser degree, irrespective of what they are attached to.
Yes, cinnamic acid is polar. Its molecular structure contains a polar carboxylic acid functional group that makes it soluble in polar solvents like water.
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.
Fumaric acid is polar. It contains carboxylic acid functional groups which make it polar due to the presence of electronegative oxygen atoms.
Polar
Phthalic acid is polar due to its asymmetric molecular structure and the presence of polar functional groups (carboxylic acid groups). This polarity allows phthalic acid to dissolve in polar solvents like water.
ethyl cinnamate
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.
Isopropyl cinnamate is the ester produced when isopropyl alcohol is reacted with cinnamic acid. This reaction typically involves an acid-catalyzed esterification process.
it is polar since it has carboxylic acid (propanoic acid) function
Fumaric acid is polar. It contains carboxylic acid functional groups which make it polar due to the presence of electronegative oxygen atoms.
Polar
butyric acid is more polar
an acid is more polar than an ester
Salicylic acid is polar due to its hydroxyl group, which creates an uneven distribution of charge in the molecule, resulting in a polar nature.
Polar
Lactic acid is a polar molecule. It contains both polar (-OH) and nonpolar (CH3) groups, but the presence of the polar -OH groups makes it an overall polar molecule.
