SYNTHESIS! Devise a multistep synthesis of the target molecules from the given starting compound. Show the reagents needed for each step and the product of each step. You may use any organic or inorganic reagents, however any structural carbons must come from bromobenzene and ethane.

Propose a mechanism for the conversion of E to F. The reagent used in this synthesis is ethyl chloroformate. The other product of this conversion is chloromethane, CH3Cl. Your mechanism should show how the CH3Cl is formed.

Starting from acetylene, propose a synthesis for the following compound. Use any other organic or inorganic reagents as needed. HO.

Design a synthesis for the compound shown. You may use any reagents and any organic compounds with less than four carbons and benzene as your starting materials. HO, O2N

Please help me with this question. Thank you.

Propose a synthesis for the molecular target below. For your synthesis you can use: the given alkyne, any hydrocarbon (compounds that contain only C and H), and any inorganic acid or base. Any other reactants must be synthesized from allowed starting materials, e.g., if your synthesis requires an alkyl halide, you will have to show how the alkyl halide is synthesized from a hydrocarbon. Target

Propose a sequence of reactions to prepare the specified target compound from the indicated starting materials.  All of the carbon atoms in the target must originate in the specified starting materials.  Keeping this restriction in mind, you may use any other organic or inorganic reagents necessary to complete the synthesis. It is only necessary to show the overall transformations involved in your proposed synthesis.

Starting with benzene and using any other reagents of your choice, design a synthesis for the following compound: CI * Incorrect. COOH A Br The target molecule above can be prepared by treating benzene with some reagent or combination of the reagents listed below. Give the necessary reagents in the correct order, as a string of letters (without spaces or punctuation, such as "EBF"). If there is more than one correct solution, provide just one answer.
