    Sir Alc KOH gives E2 reaction with 1° Carbocation than why did you use the mechanism of E1 in the very first example?

    • @rishabhbansal7373
      @rishabhbansal7373 7 років тому +2

      purvik patel , there is no formation of carbocation in E2 mechanism.

  • @shubhamagrawal6336
    @shubhamagrawal6336 7 років тому

    instead of removing h+ from o h+ can be generated by forming alkene also so why ketone has been formed

    • @shashikarsaurabh779
      @shashikarsaurabh779 6 років тому +1

      If you remove h+ from the ring then alkene is formed but in the presence of oh it is enol which is not stable and due to tautomerism effect it gets convert into keto

  • @vishalkumarthakur3296
    @vishalkumarthakur3296 7 років тому +1
