What is the acidic order of o-nitro phenol, m-nitro phenol & p-nitro phenol & why?
Can you explain the acidic order of o-nitro phenol, m-nitro phenol & p-nitro phenol & why?
Certainly! The acidic order of o-nitro phenol, m-nitro phenol, and p-nitro phenol is p-nitro > o-nitro > m-nitro. This is because the nitro group, which is electron withdrawing, reduces the electron density on the phenolic oxygen, making it more acidic. The greater the electron-withdrawing effect, the more acidic the phenol. In this case, p-nitro is the most electron-withdrawing group, followed by o-nitro and then m-nitro.
