Which one is correct ?

mainly the radical initiator is used as peroxide so addition occurs through anti markownikov rule

so except Hcl ...Hf and HI when peroxide is present then anti markownikoffs rule is used

can u ans it pls ...?

so here diff comdition occurs as anti mark addition proceeds through free radical mechanism, the addition of Hf and HI is energetically unfavouravle

got simun??

I m asking that except Hcl and Hi when peroxid is present that is anti markownikoffs rule or not

so explain this

have you seen video simun,link of which i was providing in the previous comment, you got it from there

yes

and in that video says that in case of only HBr anti markownikoffs rule is used

simun see when peroxide is used na then you go through anti mark addition as it is known to you than anti mark rule is specify and distinguish only gor halogen acids

the reason for the variability in the ratio of Markovnikov to anti-Markovnikov reaction products was due to the unexpected presence of free radical ionizing substances such as peroxides

so if you see radical initiator, it follows anti mark additions "products"

HI and HCl can't used as in these reaction one of reaction step is endothermic so reaction becomes enegetically unfavourable

tq for clearing all these

and help me how to write all the reaction of reaction mechanism

simun i sent u peter sykes book..please read one tym this book, you can surely apply mechanistic approach

and please give feedback simun and accept it

anything you want notes,books etc...please ask, i will try to make available for u

pls send me a brief and clear reaction chat can u help in this

but anti markonrule is only for HBr

yes it occurs only for HBr not for any halogen acids...as it proceeds through free radical mechanism

means can u understand it easily pls

so why here anti markownikoffs is used

see free radical addition of HCl, HI and Hf are not enegetically favourable but Hbr favours so anti mark addition occurs...now come to thiols alkene reaction...the reaction here is michael addition pathway which results in similar to anti mark addition

so here anti mark. addition proceeds

Thiol-ene radical addition occurs

https://en.m.wikipedia.org/wiki/Thiol-ene_reaction read this simun??

can u send me any image or link for the conditions in which anti markownikoffs rule is used

mainly anti mark addition occurs for HBr and all other reaction if proceeds through this, it is saying that the products seems similar to anti mark addition

got simun??

I will send a image pls check this
