 3169  251 NTA AbhyasNTA Abhyas 2020Organic Chemistry – Some Basic Principles and Techniques Report Error

Solution:

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
