2. In Experiment 4B, it was shown from the NMR spectrum that the meta-di-substituted Nitration product had been recorded as a major product: COOME COOME HNO3 H,SO, NO2 Major product However, there were two other possible but less favorable routes, i.e. ortho- or para- positions for the nitronium to attack the aromatic ring with. Draw the H-NMR spectrum for Methyl p-Nitrobenzoate in case the substitution takes place at the para-position. Pay attention to the chemical shift, the splitting pattern, and approximate the integration in your spectra. Methyl p-Nitrobenzoate 3.0 2.5 2.0 1.5 - 1.0- 0.5 4 3. 2 1. 10 6. 8.

15.Which of the following correctly explains why alkyl groups are ortho/para-directing groups? a. Meta substitution results in an arenium ion in which a positive charge is destabilized by an adjacent electron-withdrawing group. b. Ortho/para substitution results in an arenium ion intermediale in which all atoms have complete octets. c. A lone pair of electrons on the alkyl group participates in re sonance and stabilizes the arenium ion intermediate in ortho/para substitution. d. The most stable resonance structure for the arenium ion intermediate in ortho/para substitution contains a 2° carbocation. e. The alkyl group is electron donating via induction and stabilizes the adjacent positive charge in the ortho/para substitution intermediate. 5.
