Chemistry
Quick fact
In simple alkenes, the vinylic protons in cis isomers typically appear at a higher chemical shift (around 6-7 ppm) than those in trans isomers (around 5.5-6 ppm).
Why this is interesting
We know cis and trans alkenes are different, but how does a chemist tell them apart using just a magnet? NMR spectroscopy holds the answer—and it's all about which side the protons are on.

This background view organises existing cards. It is separate from the authored lessons above.
Review public suggestions and repeated searches. Approval alone does not add generator tasks.
