46. In order to determine the ident ity of an alkene, a chemist reacts it with water. She then separates the product of this reaction into two equal amounts in conta iner X and container Y. To container X, a strong oxidizing agent is added. The resulting product will react with a base to form a salt and water. When the new product in container X is mixed with conta iner Y and H2SO4 is added, the chemist is able to confirm that: H3C CH2-C-0-CH2-CH2-CH3 has been formed. The identity of the alkene is which of the folow ing? a. с. H3C-CH-CH=CH-CH,-CH, b. H2CCH d. H;C-CH=CH, 47. What is the correct IUPÁC rame for compound below? H2-CH3 -C-CH2-CH2-CH-CH a. 2-ethy-5-hexanone b. 5-ethy-2-hexanone c. 3-methy-6-heptanone HC- d. 5-methy-2-heptanone e. 2-heptanone 48.
