The p K_a values of four carboxylic acids are given below. Identify the weakest carboxylic acid.
Options
- A4.89
- B1.28
- C4.76
- D2.56
Correct answer
A. 4.89
Step-by-step solution
The more the value of p K_ a , compound will be less acidic indicating the less value of K_a and smaller the value of pK K_a , the compound will be more acidic, i.e., there will be more the value of K_a .
