trans and cis attachments to cyclic carbon structures
Posted: Sun Mar 12, 2017 2:44 pm
I am confused on how you are able to tell whether a substituent is attached trans or cis to a cyclic carbon structure. In the Introduction to Organic Chemistry textbook page 60, there is an example molecule of cinnamaldehyde, and its IUPAC name includes E because the aldehyde is attached trans to carbon three on the benzene ring. But I'm not really sure what that means or how to visualize it on the molecule?
