While discussing the SN1 mechanism, we learned that H2O is an extremely weak nucleophile. So weak that it CANNOT perform an SN2 mechanism. Analyze the properties of the oxygen atom in H20, since the oxygen is the atom that attacks in an SN1 mechanism. Which nucleophiles listed below share similarities to H20 and would be expected to be very weak nucleophiles as well? Choose- all that apply. LIOCH2CH2CH3 HOCH3 NaOH HOCH2CH2CH3 CH3CO2NA (a carboxylate) CH3CO2H (a carboxylic acid)

16. a. Label the reactive features, highlight the most reactive one, then highlight what it needs. Also, state if the reaction will start to create a carbocation, carbon radical, or carbanion, or will cause loss of aromatic character. If a carbocation, carbon radical, or carbanion starts to develop, label where that will occur. CH,CH,CH,CH,MgBr + D,0 b. Use mechanism arrows to illustrate the reaction that occurs. c. If applicable, use stabilization resources to deal with the carbocation, carbon radical, or carbanion that starts to develop during the reaction, and draw the structure of any resonance-stabilized intermediate. d. Continue labeling and diagramming the reaction until you find the major stable product(s). e. Finally, state the stereochemistry of the major product(s) and use either Fisher projection or perspective formula representations to illustrate that stereochemistry.

omplete the following mechanistic steps (#1 through 4) representing every step of the echanism: The radical chain begins (initiation) with the photochemical cleavage of a Br-Br bond, affording two bromine atoms (Br ): Br-Br Br Then, the propagation steps take place. First, the bromine atom reacts with the substrate to afford a resonance-stabilized benzylic radical. Represent this process and the different resonance forms of the resulting radical: СООН + Br HBr +
