Draw the structure of the alkyl bromide A needed to complete the synthesis of the hydrocarbon shown below. A Check CuLi Click and drag to start drawing a structure. B m ☐ G

a) This alkene can be prepared via Wittig reaction. Draw structural formulas for the aldehyde and the Wittig reagent. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • Draw the Wittig reagent in the ylide form. • If more than one combination of Wittig reagent and aldehyde is possible, draw only one set.

How can an ethanol be denatured?

Indicate the major organic product from the reaction shown. H,SO. heat

Draw out the structure of product (s). If no reaction, write No Reaction

In the reaction shown below, is 1-pentene being oxidized or reduced ?

Draw the starting reactant that would produce this alkene through a Wittig reaction. Ignore inorganic byproducts. Drawing BuLi

5. Synthesis: Synthesize the following compound from cyclohexane, any carbon pieces that are three carbons or less (can include other functional groups), and any inorganic reagents.
