Also dos anyone get oxygen for that which element ionisation number thing? I can't remember is it was period 3 or 2 and I'm shitting myself in case it's sulphur instead, as it was the 7th ionisation energy right?
Do you mean the question that gave you the table of ionisation energies? The answer was sulfur for that one
Overall I'm VERY happy with how this exam went but I feel like it was harder than the others due to new types of questions. anything got an idea of grade boundaries?
When drawing the 3 isomers Position- just change the double bond so it's on a different carbon Functional group - change it from an alkene to n alkane, remove the double c bond What about for chain isomerism?

Was sulfur mate, the jump was on the 7th electron removed and sulfur only has 6 in its valence shell.
So....I got it right? yay! I wasn't sure because I know the shape and it only had one electron pair, but I didn't know if it affected both angles by 2.5/2.
You can have either, and that is correct, I don't know why people are saying its 3 bonding pairs and 1 lone pair? That is absolute trash.
