Which has lower pk value - 2-bromopentanoic acid or 3-bromopentanoic acid and why?

3-bromopentanoic acid would have a lower pKa value compared to 2-bromopentanoic acid. This is because the bromine atom in 3-bromopentanoic acid is closer to the carboxylic acid group, making it more acidic due to increased stability of the resulting carboxylate anion through resonance stabilization.
