    and tell me that here u have not shown the fragments of molozonide why

  • Suman Kumar

    You are facing problem in molo-ozonide to ozonide. I have tried little simple

    thanks sir and tell me that here u have not show fragments of molozonide to convert it into ozonide

    eduncle-logo-app

    why

    eduncle-logo-app

    and I have done this mechanism see my solution according to book so where I m wrong

    eduncle-logo-app

    I m sending u my book solution

    eduncle-logo-app

    molonlzonide to ozonide is not direct step. second step molecule undergo addition tye reaction give ozonide.

    actually in my book they have use dufferenr method

    eduncle-logo-app

    i have sent u the picture plz see they have made two fragments of moloxinude

    eduncle-logo-app

    and sir here for cycloaddition reaction there should be 4 pie electron and 2 pie electrons

    eduncle-logo-app

    Ozone, an allotrope of oxygen, is a 1,3-dipole that undergoes [4+2] pi cyclo addtion to the above alkene.The initial product of ozone cycloaddition to an alkene is called a molozonide. Molozonides are very unstable and rapidly decompose, spectroscopic evidence for the transient existence of a molozonide has been obtained at -100 ºC.

    eduncle-logo-app

     cleavage of one of the two very weak O–O bonds in the molozonide, followed by immediate fragmentation of the resulting diradical would lead to equivalent intermediates.

    eduncle-logo-app

    the zwitterionic intermediate is a 1,3-dipole of the same type as ozone; however, it prefers to an cyclo addition to aldehyde provide ozonide
