I thought it was OK. I did Unit 3b and Unit 1 at the same time and found that Unit3b was the worst of all. Unit 1 was nice and I was just a little bit pushed for time in Unit 2.
The last question in Unit2 about chemical equilibrium was a nice question and I drew an immediate distillation flask for the aldehyde as heating under reflux would've produced a carboxylic acid. Other than that, I'm struggling to remember what else was in the paper now!
I think we can get our results on line on 11th March right? (International students)
