Among following, compound with the lowest p K_a value, is

Correct answer

0

Step-by-step solution

Strength of acid is indicated by p K_a value. Higher the value of K_a or lower the value of p K_a , stronger is the acid. Among the given aromatic acids, the strength decreases as follows Ortho-effect The effect of a group is maximum at ortho-position due to nearness, is called ortho effect.
