Why salicylic acid is stronger than p-hydroxy benzoic acid?
1 Answer
Umakant biswal
the hydroxyl group is situated closer to the carboxylic acid group , in salicylic acid than in para hydroxy benzoic acid .
this increase acidity in two ways
1- the electronegative hydroxyl group stabilise the ionise form of carboxylic acid group .
this occurs in any carboxylic acid when nearby hydrogen atoms are replaced with more electronegative atoms like oxygen and chlorine .
2- the -ve partial; charge on the oxygen atom weakly attract the hydrogen ion away from the carboxylic acid group .
which encourage dissociation .
