russian cdu topic author Out of line Senior Navigator messages: 60 Thanks received: 0	Hello everyone, I have a question about how to name an alkene or alkyne with the nomenclature R or S. Is it related to the cis and trans isomers? Thank you so much!

Regarding R and S stereoisomerism, you can watch videos on YouTube or download Professor German's organic nomenclature book. Attachments: The following user said thank you: Germán Fernández
