First question: Describe a test to differentiate between any of the carbonyl isomers of CxHy. I don't remember x,y
Second: Describe a test that would give the same result of any of the carbonyl isomers.

around 38-45 it wasn't easy it wasn't hard (although i found it harder than m/j & o/n 2014) just pray for the grade boundary to be low

really wish it's around 38-42
