Help! Chemistry unit 2 ial may 2018

so only a few days are left for our chemistry unit 2 exam and it's really difficult
all I want to ask is any tips on how to prepare and any predictions best of luck to people also
This may sound crazy. However my mum and my brother both got through their exams by reading over revision cards just before you go to bed then sleep with them under your pillow. Worth a shot
Predictions anyone? Or any questions?
how did the exam go today?

Structure 1was with double bond?

it was 400cm3


Are you sure? Because the ratio was 1:2
Why butan-1-ol was more soluble?

Na + C2H50H gives C2H5ONA +0.5 H2
