Does anybody know of a website that explains organic nomenclature ? ...something along the lines "organic nomencluture for Dummies" would be great :-)

I'm stuggling to underatand "Z-3-Bromo-6-methyloct-3-ene" let alone draw it !

Here is a site that might just be what you are looking for. There are others if this doens't fit.

Thank you very much Dr Bob222 :-) This site is great and the exercises really help cement your understanding.
