Hey guys,
Isn't HBr addition to alkenes (with NO indicated peroxide) markovnikov ? I'm confused because on this problem in achiever, the product added is anti-markovnikov (evidently because there is hv).
Is it always the case that with either ROOR or hv, HBr adds anti-markovnikov?
Also, I thought free radical bromination only occurs with alkanes (NOT alkenes)... it looks here as though HBr bromination is a radical bromination to an alkene...
If bromination is possible for alkenes, then does Br2/hv also occur on alkenes?
---- One other Achiever question---- can someone please explain what exactly choices II and III are saying?
I get that B/L acids are proton donors and B/L bases are proton acceptors but I'm having a hard time understanding what the choices are saying.
