The correct order of increasing acidic strength among the following is

  1. A phenol < ethanol < chloroacetic acid < acetic acid
  2. B ethanol < phenol < chloroacetic acid < acetic acid
  3. C ethanol < phenol < acetic acid < chloroacetic acid
  4. D chloroacetic acid < acetic acid < phenol \( < \) ethanol
Verified Solution

Answer & Solution

Correct Answer

(C) ethanol < phenol < acetic acid < chloroacetic acid

Step-by-step Solution

Detailed explanation

The correct order of increasing acidic strength is : ethanol \( < \) phenol \( < \) acetic acid \( < \) chloroacetic acid Phenol is more acidic than ethanol because in phenol, the phenoxide ion obtained on deprotonation is stabilised by resonance, which is not possible in case…
