Secondary atcohol, amide, primary amine, aromatic, ether atenolol (used to treat high blood pressure) D. Secondary alcohol, amide, secondary amine, aromatic, ester Page 1 of 7 5. Which of the following would you expect to have ionic bonds? a. CO (b.) BrNi3 d. KCl 6. How many clectrons are around Sulphur in sulphuric acid (H2SO4) ? (2. 6 b. 8 c. 10 d. 12 7. Which of the following compounds are non-polar? CO2INH3IIH2OIIIBCl3IV single best answer: A Lower pKa values result from the lower acidity of the CH bond. B. Higher pKa values result from better resonance stabilization of the conjugate base C. Lower pKa values result from better resonance stabilization of the conjugate base. (1.) Higher \( \mathrm{p} \mathrm{K}_{\perp} \) values result from better stabilization of the conjugate base by electronegative elements 9. Which of the following statements about the solubility of organic compnounds in H2O is true? 1. The non-polar part of a molecule that is not attracted to water is said to be bydrophillic. (3.) The non-polar part of a molecule that is not attracted to water is said to be hydrophobic C) The polar part of a molecule that can hydrogen bond to water is said to be hydrophiobic D For an organic compound with one functional group that contains an O or N atom, the compound is water soluble only if it has 35 carbens. 11.
