29. ta order to determine the identity of an alkene, a chemist reacts it with diluted sulfuric acid, with heatthydration), She then separates the product of this reaction into two equal amounts in container X and container Y. To container Xa strong acidizing 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 container Y and concentrated H, 50, is added, the chemist is able to confirm that HC-CH=C -CH2-CH2-CH, has been formed. The identity of the alkene is which of the following? A. D. HC-CH-CHECH-CH-CHE E. B. None of the above HC-CH=CH- C. H2C=CH 30.
