with 3b wouldn't it be amino and carboxyl because it asks for the function groups?

no because the question was
name the functional groups that link the monomers the amide functional group links the monomers? thats how i interpreted it
Shouldn't it be amide for nylon, peptide for the protein "polymer"

amide for both, they are both condensation reactions and have amide functional group

I actually think VCAA might end up accepting both answers... Both are correct answers to what, in my opinion, are valid interpretations of the question.


EDIT:

A peptide bond is just an amide bond in a biological context. They should accept either "amide and peptide" or "amide and amide".

Amide is fine for both. Peptides are a type of amide.

And vnguyen you can that's fine too.

Tony i'd say 72/77.

Isn't NaCl aqueous?
EDIT: Could you write OH-(aq) + H+(aq) => H2O(l) for the neutralisation?

nacl is salt so its solid

and yes

NaCl is soluble in water - it'd be aqueous.

Would it be ok to use sodium carbonate to test if it was only propyl propanoate?

Found it too easy.  Already lost like 10 marks from lack of care.  Also, a **** video went off through half the exam so we were treated to an earful of a man and his girlfriend as I was doing that stupid H NMR question.  Why did I put down 1- propanol.  WHY.

Most retarded exam ever.  Normally there's a really high pitched weird noise in that room.  Now we know that room is haunted by weirdness q.q

Our supervisor was BRB let's kill that video, sorry peoples.

I think I'm around 75-80%
If someone had told me that I was going to get that before I started, I would've laughed at their stupidity  8)  ;D
