(a)
Interpretation: Product formed from coupling reaction is to be predicted.
Concept introduction: Coupling can be done in many ways by using different reagents. Stereospecific products are also formed in many reactions and the product is addition of two alkyl chains.
Answer to Problem 26.20P
The product formed is,
Explanation of Solution
Species containing copper-carbon bonds are known as organocuprate reagents. These reagents act as nucleophille and react with organic halides to form coupling products which contains new

Answer to Problem 26.20P
The product formed is,
Explanation of Solution
Heck reaction is a type of coupling reaction. The reaction involves the formation of substituted alkene from an unsaturated halide and an alkene. The catalyst used for this reaction is palladium catalyst. It is a substitution reaction and replacement of H of alkene by alkylhalide takes place. The product of the reaction is
