Chapter 12.5, Problem 19P

(a)

Interpretation Introduction

Interpretation:

The resultant product obtained from the metathesis of the alkene CH3CH2CH=CH2  should be identified.

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 sp2 carbons that were not previously bonded. Alkenes also undergoes metathesis.

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.

(b)

Interpretation Introduction

Interpretation:

The resultant product obtained from the metathesis of the following alkene should be identified.
