(a)
Interpretation: The arrows that illustrate the product formed when B reacts with styrene are to be drawn. The diene and dienophile components are to be labeled.
Concept introduction: Curved arrows aid in determining the movement and flow of electrons in the reaction. The electrons that take part in the
Diene is a hydrocarbon that contains two
(b)
Interpretation: The arrows that illustrate the product formed when B reacts with
Concept introduction: Curved arrows aid in determining the movement and flow of electrons in the reaction. The electrons that take part in the chemical reactions are shown by the curved arrows.
Diene is a hydrocarbon that contains two
(c)
Interpretation: The reaction that shows the two-step sequences are to be illustrated using curved arrows.
Concept introduction: In the sigmatropic rearrangement, the rearrangement of pi bond and the breaking of sigma bond take place. This results in the generation of new sigma bond in the product. In this type of rearrangement, the number of pi bonds remains constant in the reactant as well as in the product.
