Im confused, s character of a carbon in a C-H bond makes the bond stronger if talking about homolytic cleavage, but it makes the bond weaker if talking about Heterolytic cleavage. is that right?
I'm asking because I had a quetion about which is the weakest C-H bond
in the molecule ch3-c=c-c-c=c-c-ch3
the answer was carbon 2 (counting left to right)
which makes sense because it has more S character
but yet in ochem rxn's its the allylic Hydrogen that is removed because it is the weakest bond right?
my best guess here is that carbon two is the weakest bond because of its S character and because the fact that its removal will result in a more stable molecule because it will allow resonance which will form a conjugated diene (more stable molecule)
i don't know. please provide detailed answer, thanks!
