Now plz check the mechanism onolsis h,c 0 olo3 naluntth mdo mmol030mid am's h--c cc-chee

thanku so much mam

mam the addition of ozone to alkene is 4+2 cycloaddition reaction plz explain

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

why

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

I m sending u my book solution

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

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

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

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.

 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.

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
