acidity of carboxylic acids and derivatives
What are the 4 derivatives of carboxylic acids?
certain other groups are called carboxylic acid derivatives, the most important of which are acyl halides, acid anhydrides, esters, and amides.
Among the carboxylic acid derivatives, carboxylate groups are the least reactive towards nucleophilic acyl substitution, followed by amides, then carboxylic esters and carboxylic acids, thioesters, and finally acyl phosphates, which are the most reactive among the biologically relevant acyl groups.
What is the order of acidity of carboxylic acid derivatives?
CH3CO2H
How do you know which carboxylic acid is more acidic?
If an electronegative atom is associated with carbon next to carboxylic group then the more the atom is electronegative the more is the acidity .
