QUESTION 3 Predict the structure(s) of the major organic product(s) that will form when the organic starting materials are subjected to the indicated reaction conditions. If two different organic products are formed, you should draw structures for both of them. Remember, stereoisomers are different compounds. If only one organic product is formed, draw its structure. If no reaction occurs, indicate that fact in the answer file that you submit. It is not necessary to provide structures or formulas for any inorganic byproducts that also form in the reaction. CH _4 CH, (excess)

QUESTION 4 A diazonium cation can act as the electrophile in an electrophilic aromatic substitution reaction with a highly activated aromatic ring. The resulting transformation yields a diazonium coupling product. Predict the structure of the diazonium coupling product that will form when the diazonium cation and activated benzene derivative shown below are mixed. It is not necessary to provide structures or formulas for any inorganic byproducts that also form in the reaction. din.mod NEN: Mc- CH;

QUESTIONS Propose a sequence of reactions to synthesize the target compound below from the indicated starting material. You may use any other organic and/or inorganic reagents necessary to complete your synthesis, but all carbon atoms in the target must be derived from the starting materials specified. It is only necessary to give overall transformations in answering this question. Please write out all reactions you propose to use. Draw structures for starting materials and products, and clearly indicate all reaction conditions. Please DO NOT provide curved arrow mechanisms for the reactions that you use. CH3 "NH2 Prepare from and KCN/CUCN o H3C TARGET as the sources of all C atoms in the target
