Question:

1) (20 points The electronic nature of carbonyls and carboxylates (and their derivatives) rests predominantly on the disparity in electronegativity values of the two nuclei of the functional group. For the moment, lets look at the all-carbon analog: the alkene. a. (1 point) Provide the major resonance contributor(s) for the following alkene: b. (2 points) If there exists any propensity for electrophilic or nucleophilic chemistry on either vinyl carbon, indicate so by circling the appropriate carbon and labeling it nucleophile or electrophile in the figure above. c. (2 points) For the simple aldehyde acetaldehyde, provide any major resonance structures in the space below. Acetaldehydes structure is provided to you. d. (2 points) As in part b above, indicate any nuclei that should function as a nucleophile or electrophile by circling it and labeling it appropriately. e. (2 points) In the carboxylate derivative, the ester shown below, provide any major resonance contributors, as in part a and part b above. OMe (3 points) As in part b above, indicate any nuclei that will function as potential nucleophile or electrophile by circling the nuclei and indicating their reactivity. g. (8 points) For the following sequence of structures, arrange the corresponding letters along the axis in increasing reactivity to nucleophiles. NR OMe INCREASING REACTIVITY TO NUCLEOPHILES
The electronic nature of carbonyls and carboxylates (and their derivatives) rests predominantly on the disparity in electronegativity values of the two nuclei of the functional group. For the moment, let's look at the "all-carbon" analog: the alkene. Provide the major resonance contributor(s) for the following alkene: If there exists any propensity for electrophilic or nucleophilic chemistry on either vinyl carbon, indicate so by circling the appropriate carbon and labeling it "nucleophile" or "electrophile" in the figure above. c. For the simple aldehyde acetaldehyde, provide any major resonance structures in the space below. Acetaldehyde's structure is provided to you. As in part b above, indicate any nuclei that should function as a nucleophile or electrophile by circling it and labeling it appropriately. In the carboxylate derivative, the ester shown below, provide any major resonance contributors, as in part a and part b above. As in part b above, indicate any nuclei that will function as potential nucleophile or electrophile by circling the nuclei and indicating their reactivity. For the following sequence of structures, arrange the corresponding letters along the axis in increasing reactivity to nucleophiles.
