What products are formed when cis-pent-2-ene undergoes metathesis? Use this reaction to explain why metathesis of a 1,2-disubstituted alkene (RCH=CHR') is generally not a practical method for alkene synthesis.


Expert Answer

Step 1

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 sp2 carbons that were not previously bonded.

Step 2

The products formed when cis-pent-2-ene un...
