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.

You're welcome! I'm glad you found the website helpful. Websites like this one can be a great resource for learning and understanding organic nomenclature.

When you come across a chemical name like "Z-3-Bromo-6-methyloct-3-ene" and find it difficult to understand or draw, it's important to break it down and analyze each part. Let's break down this name step by step:

1. "Z" refers to the configuration of the double bond. It indicates that the two highest priority substituents attached to the double bond are on the same side.

2. "3-Bromo" indicates that there is a bromine atom attached to the carbon at position 3.

3. "6-methyl" indicates that there is a methyl group attached to the carbon at position 6.

4. "oct" indicates that the parent chain contains eight carbons.

5. "3-ene" indicates that there is a double bond between carbons 3 and 4.

To draw this compound, start with an eight-carbon chain and identify the positions of the bromine atom and the methyl group. Then, add a double bond between carbons 3 and 4.

Using the website you mentioned, you can practice these steps and get a better understanding of organic nomenclature. Practice is key when it comes to mastering organic chemistry. If you have any more questions or need further assistance, feel free to ask!
