9. 10. Draw the product of this Lewis acid/base reaction in the box provided. F₂B+ PH, (A) (B) Which of the following is a true statement regarding the equilibrium shown? Br & COOH Molecule 3 is the stronger base so the equilibrium favors the reactants Molecule 3 is the stronger base so the equilibrium favors the products Molecule 3 is the weaker base so the equilibrium favors the reactants Molecule 3 is the weaker base so the equilibrium favors the products (C) (D) (E) Molecule 3 is the weaker base so the equilibrium favors neither direction A) Ethyne etheneethane B) Ethene ethyne < ethane C) Ethane ethyne < ethene D) Ethane ethene < ethyne. E) Ethene < ethane < ethyne coo 11. The compounds ethane (CH-CH:), ethene (C2H4), and ethyne (C₂H₂) exhibit this order of increasing acidity: 12. Which of these is not a true statement? A) All Brensted-Lowry bases are also Lewis bases. B) All Lewis acids are also Bronsted-Lowry acids. CH I A) 4>1>5>2>3 B) 1>4>2>3> 5 C) 1>5>4>2>3 D) 3>2>5>4>1 E) 1>4>5>2>3 product C) All Brønsted-Lowry acids contain hydrogen. D) All Lewis acids are electron-deficient. E) According to the Bronsted-Lowry theory, water is amphoteric (both an acid and a base). 13. Rank the following compounds in order of decreasing acidity. NH₂ 4 H₂S 2 HI 3 COOH CH,OH
