Wait did they ask us how to distinguish between the enantiomers because I didn't see that?

No they didn't. Don't believe anyone who says there was.

That question was NOT on the paper.

Thank you!! at least havent lost those marks...

yeah i think it did

I think it asked for the section of the polymer not the dipeptide

Why did you get it wrong?

I said if the reaction is endothermic or exothermic the temp will change which will affect the rate,pretty sure I got it totally wrong tho :frown:

For the question that asked about separating the alcohol/collecting it - I said heat under reflux - is this right?

trailing as it asked for a section of it

I'm sorry but it was definitely a dipeptide...it didn't exactly look like there were going to be trailing bonds, did it?

I don't remember it asking us how to distinguish between the two enantiomers!

DID I MISS A QUESTION OUT!! I NEVER TALKED ABOUT ROTATING PLANE POLARISED LIGHT ....

haha don't worry I am too, I honestly think I've definitely dropped about 16/17 marks, and then some :frown:

I need atleast an A in this, and I've dropped like definitely 20 marks already assuming I think I did the other questions right :frown:

I drew it as the dipeptide and now this is really stressing me out! :frown:

Do you know what's really annoying me about this paper? The pathetic one markers and HSW questions that pretty much just test about 1% of our knowledge. It's so annoying that I actually got the 9 marker at the end and a few of the other longer mark questions, but these stupid one markers and HSW questions have let me down big time and have cost me a grade :frown:

I hope you're happy AQA... ****s

There were 2 repeating unit questions on the paper. They wouldn't have put another one in for the bants...it said you had to add atoms AND bonds

I missed out quite a few questions and I can't even remember what they were.. probably about 10 marks worth that i didn't have time to come back to, but i also lost around 5 marks on the last question because i didn't finish. I also lost marks for the paper generally being hard so probably at least 10. that means I've already lost about 25 marks... :redface:
