[PDF] Carboxylic Acids PDF Ch20.pdf

A carboxylic acid donates protons by the heterolytic cleavage of the O-H bond, The carboxyl group takes priority over any other functional groups previously Values of pKa for common alkyl carboxylic acids are around 5 (Ka ~ 10-5)

Approximate pKa chart of the functional groups: values to know 1 Protonated carbonyl pKa = -7 Other important pKa's 2 Carboxylic acid pKa = 4-5 4

amines are considerably more acidic than alkyl amines (pKa < 5) The nitrogen lone pair is nitriles, amides, and nitroarene can be reduced to the corresponding react with only the most easily reduced functional groups, such as an iminium
