Carboxylic acid pi bonds
http://webhome.auburn.edu/~deruija/pda1_acids1.pdf The strength of a carboxylic acid depends on the extent of its ionization constant: the more ionized it is, the stronger it is. As an acid becomes stronger, the numerical value of its pKa drops. In acids, the electron-releasing inductive effect of the alkyl group increases the electron density on oxygen and thus hinders the breaking of the O-H bond, which consequently reduces the ionization. Due to its greater ionization, formic acid (pKa=3.74) is stronger than acetic acid (pKa=4…

WebOct 7, 2024 · This results in a positively charged carboxylic acid derivative, which is then deprotonated to give the neutral carboxylic acid, completing the hydrolysis of the amide. This six-step mechanism (protonation, addition, deprotonation, protonation, elimination, deprotonation) might seem vaguely familiar. WebJan 28, 2024 · During the first step of the mechanism, the carboxylic acid reactant acts as a nucleophile and attacks the electrophilic sulfur of thionyl chloride, pushing the pi electrons of the S=O bond onto oxygen. Reforming the S=O bond and eliminating a cloride anion (Cl -) as a leaving group creates a protonated acyl chlorosulfite.
