Question

In the following reaction, experimentally one finds that if the concentration of the 13. doubled. One also finds that if the doubled, then the reaction rate is alkene is concentration of water is doubled, the reaction rate remains the same. Which of the statements correctly describes the kinetics of the reaction? There may be more following than one correct answer. (1 point) A) The reaction is first order in alkene B) The reaction is zero order in water C) The reaction is first order overall D) The reaction is zero order in H2SOs E) If the reaction temperatu elevated by 10 c the rate will double F) All of the above G) none of the above 14. Which of the following groups do not contain an spa hybridized atom? (1 point) A) BF3 B) 3 carbocation C) Methyl carbanion D) 2° alkyl radical E) Carbonyl group F) Ethene G) PH3 15. When ionization occurs at the single stereocenter of a chiral compound, the resulting carbocation is: (1 point) A) Chiral B) Achiral C) Optically active D) Racemic E) Diastereomeric F) All of the above 16. Which of the following statement(s) correctly describes E2 reactions of alkyl halides (RX) (1 point) A) Rate klbasej B) Rate k[RX][base] C) Rat i k[RX] D) Rearrangements are sometimes seen F) The reaction occurs in two or more distinct steps
