CHM412 Jan 2013 Past Years Paper

Feel free to leave Q’s about this paper.
BEFORE ASKING: please mention Q number and part as well as your current understanding/answer.
Tq

Simple Analysis
Q1: Structures from given names: 10 marks
Q2: Names from given structures: 10 marks
Q3: “Aspects/Features” of molecules, identifying functional groups  chiral centres(!) hybridization, demonstrating H-bonding IMF’s 12 marks
Q4: Chemical reactions of various functional groups.12 marks

Again note that almost half the total number of marks are available for very unchallenging questions. You need to maximise scoring on these Q’s in order to cope with any mark losses on the harder, more tricky questions.

Q5: Identifying the type/named reactions (e.g. “Nucleophilic Addition” type of reactions). 3 marks
Q6: Identifying/sketching amines, explanation of different basicities, reaction with NaNO2 + HCl at icebath conditions. 11 marks
Q7: Carbonyl chemistry – reaction with cyanide and MECHANISM! 9 marks.
Q8: Reaction pathway scheme, reactions of various functional groups and chemical tests (i.e. strongly related to lab work) to distinguish different functional group 13 marks
