this year 12 chemistry looks like a bit of a step up from year 11 lolJust some hints:
E is a tertiary alcohol (2-methylbutan-2-ol) as it is not oxidising by the oxidising agent
C is 2-bromo-2-methylbutane as it makes E through a substitution
A is an alkene. It is 2-methylbut-1-ene. It must be the but-1-ene bit because it needs to make a primary alcohol to make the carboxylic acid in compound F
B is 1-bromo-2-methylbutane. Other isomer of the addition reaction of HBr
D is 2-methylbutan-1-ol
F is a carboxylic acid
G is a sodium salt
H and I are made because it can react two ways either alcohol + carboxylic acid = ester
or amine + carboxylic acid = amine
Haha yep. The stuff in that question is organic chemistry, which looks a lot more confusing than it is!this year 12 chemistry looks like a bit of a step up from year 11 lol
I'll try my best to enjoy it ahah, good luck in your examsHaha yep. The stuff in that question is organic chemistry, which looks a lot more confusing than it is!
Year 12 chem is pretty complex but also super rewarding, so enjoy it!
Yeah haha also keep in mind the BOS trials are usually harder than the HSC if you want to challenge yourself! They're worth a try to improve problem solving skills and to see where you're at ^^this year 12 chemistry looks like a bit of a step up from year 11 lol
Will just outline it here, because it is quite long to type in full.Hi.
Are you able to provide me with the answers to Q13 b) i) for the Maths Ext 1 BoS 2020 Trials paper please? Thank you!
P.S. hats off to you for this Q. I have never been stumped by an Induction question. Really, really made me think.
How did you get the definition of (Will just outline it here, because it is quite long to type in full.
You need to prove
Use the definition of
But
and
Hence
You can then apply the assumption to get the final answer.
And (from what i can see from that definition) you can't use the roots and coefficient rules?How did you get the definition of (
hiii roughly when will the chem answers be uploaded?Pending someone giving that, feel free to name a handful of specific questions you want to know the answer to and we can provide a brief outline of the solution.
Use this on the RHS of what you are trying to proveHow did you get the definition of (
Note that and are the roots of the equationAnd (from what i can see from that definition) you can't use the roots and coefficient rules?
Sorry, there is a bit of a backlog in getting Maths out before Chemistry as the Maths HSC exams start on Monday and the Chemistry HSC is still a while away. If you have any specific questions you want to know the answer to, just post it here.hiii roughly when will the chem answers be uploaded?
when will the math solutions be uploaded considering the exams are in a few days?Sorry, there is a bit of a backlog in getting Maths out before Chemistry as the Maths HSC exams start on Monday and the Chemistry HSC is still a while away. If you have any specific questions you want to know the answer to, just post it here.
Maths Ext2 results and solutions will be released tonight...when will the math solutions be uploaded considering the exams are in a few days?
seemed like the marker had a great time marking q16!!! ;DAye good job to the person who got 72! Well done to everyone else as well.
Seems question 16 destroyed everyone this year.
