Answer:
Trinitrobenzoic acid > para nitro benzoic acid>benzoic acid
Nulceophilic acyl Substitution increases by electron withdrawing group (NO2) more the no of withdrawing groups more the reactivity
Since withdrawing group increases positive charge hence nucleophilie readily reacts.
Acidity of Carboxylic acid is explained by inductive effect
Withdrawing group (halogen) increases the acidity and acidity decreases with increasing the distance between halogen and COOH group
And lower the acidity higher the pka and Vice-Versa.
Hence 2-Chlorobutanoic acid has lower pka and more acidic than 3-chloro and 4-chlorobutanoic acids
