What does it mean when the AQA A-level Chemistry says “ MS 4.1, 4.2 and 4.3: Students understand the origin of E–Z isomerism” I’ve seen an exam question were it uses the phrase “origin in isomerism” but I don’t know to even begin to answer.
You can find the link here where it talks of it here. https://www.aqa.org.uk/subjects/scie...stry/isomerism
Any help would be much appreciated.

correct.
i'd also add on the fact that there are 2 different priority groups on each carbon
