and there was 2 intermediate alkenes making it cus there was 2 arrows going into it

I think it was okay until 2 exams are generally the same questions are simple but they throw in a few ones that are a bit weird wasn't too fond of the last one and the radical substitution one, all my class got a range of different values for the enthalpy change (like so varied it wasn't just because of the differences in what temp change you got) so would be curious to know what others got?

Did anyone else do curly arrows in the radical substitution, idk if that was me being excessive or not but I did single headed arrows showing the pathway of electrons

I think that was like -213? Or around that maybe -132? I can’t quite remember it was in that ballpark though

Also for the 10 marker I think I got it wrong I put petan-1-ok but I’m fairly sure there was 1 maybe two methyl groups now that I’m rethinking it

I think it was something like 2.2 dimethylpropanol or that's what I think I drew

pretty sure it was butanol with a methyl group somewhere doesn't really matter what u got as long as u analysed what they gave you the actual compound is only a mark
