Concept explainers
Interpretation:
The products obtained from metathesis of the following
Concept introduction:
Alkene Metathesis Or olefin metathesis
This breaks the double bond of an alkene and then rejoins the fragments. When the fragments are joined, the new double bond is formed between two
Terminal alkene gives the best yields of a single alkene product in metathesis because one of the products is ethane, which is equally removed from the reaction mixture, thus shifting the equilibrium in favor of the other new alkene product.
