2. Which reagent has an sp hybridized carbon in the center of its Et? 3. Which of thene reactions will have Fex 4 as a nucleophile in the second step? 4. Which of these reactions will have an sp2 hybridized carbon that can wisud up with a posithve charge (hint: it is called an acrlium ion)? 5. What is the nucleophile in each of the above reactions? 6. Draw each electrophile indicated in the spaces provided below. 2. Which reagent has an sp hybridized carbon in the center of its Et? 3.
