what was the shapes around the carbon atoms
was it trigonal planar and tetrahedral.

 

[help2024]

do you think I can get one mark for writing the dissociation equation for last q or no?

 

[Ishi081]

in the second last question how many marks would I get if I calculated the mass of the halogen and found it to be bromine (but later on wrote the wrong compound writing F - idk how I ended up doing that) and I got the structures of A and B (except the Flourine part) but not E with the correct justifications for A and B?

Often for a 4 mark calculation question you can get 1 mark for 'some relevant information', 2 for 'provides some steps of the calculation', 3 for 'provides most steps of calculation' and obviously 4 is getting it correct. So i would guess you would get a mark. probably 3 for those of us who forgot to subtract and got .53 or whatever it was. actual answer 0.39 im pretty sure

thats what i said as well but i had no idea lol

will 87 be b6 cutoff?

 

[appleali]

no chance

mr janus,
ive heard usually in hsc marking that the first solution is marked and anything past it is disregarded.
i am open to other opinions.
regards

probably about that. maybe a little higher because i think that was a relatively easy test

yep it was

probably lose 1 mark for swapping Br with F ( they should be able to see what you meant to do but cant give you all the marks obviously). maybe 3 or 4 out of 7 in total if you didnt get anything to do with compound E? idk really tho

yep it was

u done?

okay so at least 3?

 

[herbimycin]

Yeah probably 3. would be 4 for getting the first two correct but -1 for swapping the halide. Did you write anything about E or what it can/cant be? bc that will sometimes get you an extra mark

nah still physics left to go, gotta hustle it

yeah i got geo man. i have no motivation especially after chem

ahh thats the last exam aye, good luck
fr the post chem motivation is at an all time low

real I have phys aswell and at this point i dont even care abt my hsc I just wanna be free - everyone else is alr out celebrating smh

Q35 was "Identify which structures 1, 2 and 3 in the table are acids X, Y and Z. Justify your answer with reference to the information provided." Surely we dont have to refer to it all, they gave so much info that you didn't really need

Well hopefully they don't mark too harshly for that - sucks since I got everything right just forgot abt doing that stuff

i said trigonal planar and pyramidal cos i forgot name for tetrahedral would i lose a mark?

Yeah had to be tetrahedral
