Cyclopentadiene

Good. Values are all correct. Interesting discussion!

Taxol

Excellent discussion of 9 and 10! For the olefins, there’s a lot more you could have said; you’ve said they are hyperstable but haven’t really explained why.

NMR

1H NMR – Good discussion

13C NMR- Have a look in to heavy atoms and the effect they have on NMR. This is the reason for the large deviations you have seen. A closer look will show this comes from the carbon next to the sulfurs.

The tables should be aligned so you can clearly see comparisons and assignments

Epoxide

Crystal structure

Well done! Loads of interesting information.

NMR

Good. Nice conclusion.

Rotations

How reliable are the literature values? Are these the only ones you found? There’s likely to be a greater variation than this!

TS

Free energy only calculated for half! What about the other catalyst? This section is worth the most if you check the mark scheme so sadly lots of marks lost here :( .

QTAIM and NCI

More information could have been teased out here, more discussion would have helped!

Suggestion

Good, but you were told to find ORP>+500!
