Cpd dimers: It would have been nice to see some jmols of your structures. Good to see you relating energies to structural features of the molecule.

Taxol: Good to see you investigating different conformations regarding the six membered ring. However, have you thought that there may actually be further chair conformations? Your explanation of hyperstable alkenes could have been better.

Carbene: Good to see you outlining the weaknesses of MM. Good answer.

Glycosidation: Your explanation of glycosidation is not the full picture, is just SN2 involved here? Think further than ‘electron interactions’, MOPAC can form new bonds whereas MM2 can’t. Can you notice any similarities between energies of A and B?

Taxol NMR: Your analysis could have been a little better. For instance, the comparison of two lots of numbers in a table is not a particularly reader friendly method to show the similarity of your results. A bar chart, in this case, would have been much more useful.

Mini-project: Maybe not the best choice of molecule, there is obviously a lot of conformational freedom in this structure. But good to see you’re trying to investigate a number of different conformations. Again, a clearer analysis of your results would have been beneficial. As a summary, could we actually us the predicted 13C NMR to differentiate between the isomers?

Overall: Your English could use a little work, although it did improve as the report went on. A good effort
