    The attacked of DMSO at Bromonium ion why took place from less substituted side why not from the other side ? Please help me to clear this doubt .. At 9:47

    • @Chemistrylover

      actually that will not attack on less sustituted side, I just wanted to show that bromonium ion will be generated and DMSO will attack on it.
      And indeed it will attack on more substituted side.....what happens for a SN1 type rxn.
      I just casualy showd that.

    At 10:04 min why not DMS elimination occurs, which is common in many DMSO based oxidation reactions.?

      I think positively charged S is more susceptible to attack by water molecule.

    Sir I have one doubt - when you attck the bromonium ion by DMSO then you show that DMSO attck on less substituted end of bromonium ion but I think when thre is positive charge on any 3+ membered ring then any nucleophile prefer to attack at more substituted side....... Plz sie reply

    That means Reaction with NBS / light give Radical reaction and Reaction with Br2 give addition product ? If cyclohexene react with Br2 then we get dibromo cyclohexane ( addition product ) right ?

    • @Chemistrylover
      @Chemistrylover  6 років тому

      Yes....If u have large amount of Br2 u will always get addition pdt....
      To get allylic bromination u need to control the amount of Br2 ...And that is done by using NBS
