From Full Structural Formula to Skeletal Structural Formula
The other way of "compressing" the full structural formula is the condensed structural formula. In a condensed structural formula you write out the formula as a string, e.g., CH3CH2CHOHCH3.
While we often condense part of the structure like a -CH3 or -OH fragment, we don't usually use it in full because it is not capable of showing cyclic structures.
Try the examples in your notes.

Drawing Diagrams in Miro
Consider signing up for an educational license for Miro. We will use this as a collaboration tool in the future.
- Sketch the diagrams on paper; then
- Convert it into a Miro drawing. Use either the class drawing, or create your own board.
Consider going through your 4 weeks' notes and annotating all of this on your Miro board.
You can bring a half-A4 page crib sheet for your first test (H-20). Start thinking about how you can use the page!
You may find it surprising that I referred to a structural formula (either kind) as having similar information content as that of a 3-dimensional representation. "What about the lengths and angles?" It turns out that many aspects of those are very predictable: you will learn about them as VSEPR and bond lengths in the future.
Most people say they hate group work. I'd argue working in a group requires
- Skills that they have never learnt, and
- Tools that they have never had
Anyone would "hate cooking" if they are asked to invent it from stone age conditions. We will try to build the skills and get the tools before sending you in the deep end.
