The correct answer is: 2-chloropentanoic acid
As magnitude of –I effect decreases with distance so acidic nature also decreases.
Here 2-chloropentanoic acid is most acidic while 5-chloropentanoic acid is least acidic.
2-chloropentanoic acid > 3-chloropentanoic acid > 4-chloropentanoic acid > 5-chloropentanoic acid
