CH309 Section 03 Organic Chemistry Name:_______________________________ Quiz 2 Chapter 16 25 (+2) points February 2, 2010 (6 pts.) Provide the mechanism for the formation of the kinetic and thermodynamic products for the reaction below. Place the products in the appropriate box labeled kinetic pdt. and thermodynamic pdt. Circle the product in the box that is the most stable. Provide the IUPAC name of the starting material. (You must assume that there is only one equivalent of reagent (HCl) because I just told you so!). Don’t worry about showing the stereochemistry of the products. H Cl + IUPAC Name:_____________________________ + kinetic pdt. thermodynamic pdt. (3 points) Provide the product for the following reaction. No mechanism, just the major product. O O O + (4 pts.) What diene and dienophile are needed to prepare the following Diels-Alder product? C H 3 C H 3 Cl O O CH 3 + diene dienophile Diels-Alder product

Unformatted text preview: Provide the structures for the two products, in the boxes below, based on your understanding of reaction intermediate stability, intramolecular cyclization reactions, and suggested homework problems (i.e. hint, hint, hint/wink). H Br (1 eq.) + (4 pts) Provide the structure for the one product of the following Diels-Alder reaction. O OH O O H + Diels-Alder Product (2 pts) Provide the hybridization at the carbon atom pointed at by the arrow. CHCH 3 _ Hint, this is a negatively charged carbon atom. Bonus: (2 pts) Given ROYGBIV, and the fact that a red tomato is red, fill in the blanks. Red tomatoes appear red because they absorb light at a wavelength of approximately _______ nm and reflect light at a wavelength of approximately ________ nm.
