(a) Interpretation: The product formed for the given Diels-Alder reaction in which compound containing triple bond is Diels-Alder dienophiles is to be drawn. Concept introduction: Diels-alder reaction is a cycloaddition reaction in which two molecules combine to form a new ring. In this type of reaction, syn addition takes place. It is a reaction between diene with a dienophile to yield a cyclohexene. The dienophile adds to one side of the diene, and diene adds to the one side of the dienophile. Thus, they have syn stereochemistry.

Question

2. Please rank the following dienophiles in their rate of reaction with the same diene in a Diels-Alder reaction (i.e. 1= fastest or most reactive dienophile, 4 = slowest or least reactive dienophile). Put your answer on the line below each structure. 3. Please rank the following dienes in their rate of reaction with the same dienophile in a Diels-Alder reaction (i.e. 1= fastest or most reactive diene, 4 = slowest or least reactive diene). Put your answer on the line below each structure. OMe OMe OMe |

Compounds containing triple bonds are also Diels–Alder dienophiles. With this in mind, draw the products of each reaction.

Would like help drawing out this mechanism step by step please. I need to know to how each step follows the other. Not one drawing with a million arrows please
