- Rank the labeled protons in the following molecule in order of increasing pKa. PHO H,arrow_forwardWhich nitrogen in the aromatic compound below is the least basic?arrow_forwardComplete the following paragraph regarding the structures below, then draw a relevant resonance contributor to support your selections in the paragraph. Your resonance contributor could be drawn to show either why one acid is stronger or why one acid is weaker. :0: .H B :0: A Compound [A/B] is the stronger acid because it is an electron [ withdrawing / donating ] group. By [increasing / decreasing ] the electron density on the ring, it will [ stabilize / destabilize] the conjugate base, and the [more / less ] stable the conjugate base, the [ stronger / weaker ] the acid. The resonance contributor below shows how electron density is [ withdrawn / donated ] to compound [A/B] showing it is the [ stronger / weaker ] acid resonance contributorarrow_forward
- Rank the labeled H atoms in the following compound in order of increasing acidity.arrow_forwardDraw both resonance structures of the anion formed by the reaction of the most acidic C-H bond of the compound below with base.arrow_forwardPropose a structure consistent with each set of data.arrow_forward
- Provide the complete mechanism using curved arrow formalism for the reaction of p-isopropxlbenzoic acid undergoing nitration. Tell how many peaks in the 'H and 13C NMR spectrum that would be observed for the final product.arrow_forward9. Compound A is treated with HONO, followed by a reaction with Compound B; the final product obtained is shown below. H NMR spectra for Compounds A and B are provided. (a) Provide structures of Compounds A and B in the boxes below. (b) Label the signals on each spectrum with letters (as outlined on Week 3 Tuesday slide 4), then assign all H NMR signals to specific chemical environments or specific protons on the structures of Compounds A and B.
