Most Important Selected Qs for JEE AdvancedChemistryAldehydes and Ketones

Consider the two reactions i.e. halogenation and isotopic substitution given. When kinetics studies were carried out for both reactions, it was found that their rates were similar when identical reaction conditions i.e. acid/base were used. Based on this statement what can you infer about the reaction?

Options

  1. ABoth reactions have a common intermediate and its formation is the rate determining step
  2. BBoth reactions have a common intermediate and its formation occurs after the rate determining step
  3. CBoth reactions have different intermediates
  4. DThe halogenation will be unaffected by concentration of bromine

Correct answer

D. The halogenation will be unaffected by concentration of bromine

Step-by-step solution

formation of enol or enolate is the RDS. Hence the rate of reaction is unaffected by the nature or concentration of halogen
