CHM412 June 2012 Past Years Paper

No content yet, but 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: 12 marks
Q2: Given a molecule (alkane) asked to identify chiral centres(!), molcular and empirical formula, combustion equation, hybridization: 10 marks
Q3: Put names to molecular structures given 12 marks
Q4: Reactions of alkenes and other functional group interconversions (alkenes/haloalkanes/carbonyls/alcohols) and chemical tests on those those groups.: 10 marks

Once more, like the two more recent (2013) past years papers, the questions have been quite ‘shallow’ – i.e. no ‘deep’ explanations needed to explain these things. Their should be no problem with getting FULL (or almost full) marks up to this stage.

Q5: Which molecule is most acidic  – EXPLANATION required. Hydrolysis chem equation, Reaction of an acid chloride (specifically ethanoyl chloride) in making an ester and an amide.: 10 marks
Q6: Six chemical reactions/functional group interconversions of various (non-related molecules): 12 marks
Q7: Multi-step reaction scheme alcohol->ester, alcohol->alkene, alkene->alkane, alkane->chloroalkane, Friedel Crafts alkylation: 14 marks

Nothing too difficult, almost no explain type questions (the ones students find hardest/worst to answer)
