Interpretation:
Whether the mechanism for the reaction of cyclopentene with
Concept introduction:
Alkenes metathesis is a reaction between two alkenes which results in the interchange of double bonds of carbon atoms with the catalyst. It is also known as olefin metathesis and the catalyst used for this reaction is Grubbs catalyst.
(b)
Interpretation:
The result which is predicted by the two mechanisms: Pairwise mechanism and metallacycle formation mechanism for the ratio of the three ethylene products formed in the reaction of
