What can be A and B in the following reaction?

Options

  1. AA. HBr B. alc. KOH
  2. BA. HBr , Peroxide B. alc. KOH
  3. CA. HBr , Peroxide B. aq. KOH ,
  4. DA. HBr , B. a q . KOH ,

Correct answer

C. A. HBr , Peroxide B. aq. KOH ,

Step-by-step solution

The conversion of propene ( CH ₃ CH = CH ₂ ) to 1-bromopropane ( CH ₃ CH ₂ CH ₂ Br ) is an anti-Markovnikov addition of HBr. This reaction occurs in the presence of organic peroxides (Kharasch effect or peroxide effect). Thus, reagent A is HBr with peroxide. The conversion of 1-bromopropane ( CH ₃ CH ₂ CH ₂ Br ) to propan-1-ol ( CH ₃ CH ₂ CH ₂ OH ) is a nucleophilic substitution reaction. Alkyl halides react with aqueous potassium hydroxide ( aq. KOH ) under heating to undergo hydrolysis, yielding the corresponding
