Now that you have seen the exam, what do you think the b6 cutoff will be?
Multiple choice this year is probably easier than previous years. Short answers hard to say because the syllabus is so different. I estimate low 80s as usual for ChemNow that you have seen the exam, what do you think the b6 cutoff will be?
I personally would give it but as I said before try to not take these for 100% correct, NESA may mark easier or harderWait, are you sure we need diagrams for the boiling point question?
What if I gave a lot of analysis about hydrogen bonds and permanent dipole-dipole forces in depth
Hopefully, you're rightMultiple choice this year is probably easier than previous years. Short answers hard to say because the syllabus is so different. I estimate low 80s as usual for Chem
oh no i thought that thiols were non polar due to the weak electronegativity between the S-H bond!OTHER SOLUTIONS (I HAVE REACHED THE MAX 10 ATTACHMENTS)

It is still very weakly polar because there is a net-dipole. Although small still has some effect. If you have justified properly you may be okayoh no i thought that thiols were non polar due to the weak electronegativity between the S-H bond!
Okay, I justified it by referring to electronegativites and showing that it has a greater tendency to form temporary dipoles from Van der Waals forces rather than permanent dipoles, is that good enough?It is still very weakly polar because there is a net-dipole.

Yeah should be okay, at most you will lose a mark if it is wrongOkay, I justified it by referring to electronegativites and showing that it has a greater tendency to form temporary dipoles from Van der Waals forces rather than permanent dipoles, is that good enough?
Okay thanks, and also for the final q will I lose a mark for not restating the equations? Because I ran out of space, but i described rhe by products and reagentsYeah should be okay, at most you will lose a mark if it is wrong
Thanks!Goodnight everyone Hopefully I didn't scare you too much with the solutions haha, I am sure you will all do fine
Will fix that tomorrow morning thanks for letting me know24 b is missing the number of marks but besides that all g tysvm
