Final answer:
When 1-hexene is treated with Grubbs catalyst, the main products obtained are 1,5-hexadiene and ethene. The thermodynamic driving force for this reaction is the stability of the reactants and products.
Step-by-step explanation:
Olefin metathesis refers to a chemical reaction that involves the rearrangement of carbon-carbon double bonds. When 1-hexene is treated with Grubbs catalyst, the main products obtained are 1,5-hexadiene and ethene. This reaction is known as cross-metathesis, where the double bond in 1-hexene is cleaved and forms new bonds with ethene, resulting in the formation of 1,5-hexadiene and ethene.
The thermodynamic driving force for this reaction is the difference in the stability of the reactants and products. In this case, the formation of 1,5-hexadiene and ethene is thermodynamically favored due to the release of energy during the formation of new carbon-carbon double bonds and the stabilization of the resulting products.
