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?

The addition of water to aldehydes and ketones occurs rapidly, although it is not thermodynamically favored. What would be the product for the reaction above? Hint: Think of the self-ionization of water and the polarity of the carbonyl group.
Zaitsev's rule: states " The alkene formed in greatest amount is the one that corresponds to O A. removal of the hydrogen from the alpha-carbon having the fewest hydrogen substituents O B. removal of the hydrogen from the any-carbon having the fewest hydrogen substituents OC. removal of the water molecule from the alpha-carbon having the fewest hydrogen substituents D. removal of the hydroxyl (OH) from the any carbon having the fewest hydrogen substituents O E. addition of hydrogen to more substituted carbon atom Reset Selection Previous Next Save 26°C Sunny DELL 立
Vhich of the following statements is incorrect? * 3 p Hammond-Leffler Postulate states that there is a strong resemblance between the transition state and the product in an endothermic reaction. Hammond-Leffler Postulate states that there is a strong resemblance between the transition state and the reactants in an exothermic reaction. The presence of more electron-donating alkyl groups ineffectively delocalize the positive charge in an organic molecule, making it less stable. The dehydration of primary alcohol proceeds via E2 mechanism. All of the abovę
the bonds in the alkene compounds are sigma and bi bonds true or flase
Please answer this Can you give examples to explain Addition reactions-general characteristics Benzene rings do not reactthi like alkenes Remember, the electrophile adds to the less substituted carbon, and the nucleophile to the more substituted carbon. Markovnikov’s Rule: The addition of a hydrogen halide to an alkene favors the product in which the proton adds to the alkene carbon that is initially bonded to the greater number of hydrogen atoms. Carbocation rearrangements- Methyl groups and hydride groups can migrate to make a more stable carbocation. A primary carbocation is less stable than a secondary carbocation, which is less stable than a tertiary carbocation. Addition of A Strong Bronsted Acid Hydrohalogenation HX addition to an alkene. Goes through a carbocation intermediate. The electrophile (H+) adds to the less substituted carbon, and the carbocation forms on the more substituted carbon. The nucleophile (X-) then adds to the more substituted carbocation.…
