- You are required to synthesize 2-bromopentane from the reaction between an alkene with HBr. Which alkene, 1-pentene or 2-pentene, should you react with HBr in order to get 2-bromopentane? Give an explanation.arrow_forwardA chemist allows some pure (2S,3R)-3-bromo-2,3-diphenylpentane to react with a solution of sodium ethoxide(NaOCH2 CH3) in ethanol. The products are two alkenes: A (cis-trans mixture) and B, a single pure isomer. Under the same conditions, the reaction of (2S,3S)-3-bromo-2,3-diphenylpentane gives two alkenes, A (cis-trans mixture) and C. Upon catalytic hydrogenation, all three of these alkenes (A, B, and C) give 2,3-diphenylpentane. Determine the structures of A, B, and C; give equations for their formation; and explain the stereospecificity of these reactions.arrow_forwardA synthetic organic molecule, G, which contains both aldehyde and ether functional groups, is subjected to a series of reactions in a multi-step synthesis pathway. In the first step, G undergoes a Wittig reaction, leading to the formation of an alkene, H. Subsequently, H is treated with an ozone (O3) reagent followed by a reducing agent in an ozonolysis reaction, resulting in the formation of two different products, I and J. Considering the functional groups present in G and the nature of the reactions involved, what are the most probable structures or functional groups present in products I and J? A. I contains a carboxylic acid group, and J contains an aldehyde group. B. I contains a ketone group, and J contains an alcohol group. C. I and J both contain aldehyde groups. D. I contains an ester group, and J contains a ketone group. Don't use chat gpt.arrow_forward
- Alkenes can be converted into alcohols by acid-catalyzed addition of water. Assuming that Markovnikov’s rule is valid, predict the major alcohol product from the following alkene.arrow_forwardthe action of halogenated derivatives of alkanes with KOH: CnH2n + 1 Cl + KOH = CnH2n + 2O + KCl is: a) radical substitution b) nucleophilic substitution c) electrophilic substitution d) addition reactionarrow_forwardZaitsev’s rule: states " The alkene formed in greatest amount is the one that corresponds to A. removal of the hydrogen from the alpha-carbon having the fewest hydrogen substituents B. removal of the hydrogen from the any-carbon having the fewest hydrogen substituents C. 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 E. addition of hydrogen to more substituted carbon atomarrow_forward
- 1,4-Dioxane is made commercially by the acid-catalyzed condensation of an alcohol.(a) Show what alcohol will undergo condensation, with loss of water, to give 1,4-dioxane.arrow_forward#B: Methyl acetate has methoxy, -OCH3 as the remaining of the alcohol part in the ester. Isopropyl acetate has isopropoxy, -OCH(CH3)2 as the remaining of the alcohol part in the ester. -OCH(CH3)2 is more electron donating than the methoxy, -OCH3 group due to the presence of two electron-donating -CH3 group in the former. Hence saponification reaction of Isopropyl acetate is much slower than methyl acetate. Hence the rate of saponification of methyl acetate, CH3CCO2CH3 is 50 times greater than that for isopropyl acetate.arrow_forwardA problem often encountered in the oxidation of primary alcohols to acids is that esters are sometimes produced as by-products. For example, oxidation of ethanol yields acetic acid and ethyl acetate: Propose a mechanism to account for the formation of ethyl acetate. Take into account the reversible reaction between aldehydes and alcohols:arrow_forward
- The following alcohol has been subjected to acid-catalyzed dehydration and yields a mixture of two isomeric alkenes. Draw the two alkenes, the major and the minor product as predicted by the Zaitsev rule.arrow_forwardExplain this ? "Organic synthesis is the systematic preparation of a compound from areadily available starting material by one or many steps".arrow_forward2,4,6-Trinitrophenol is known by the common name picricacid. Picric acid is a solid but is readily soluble in water. Insolution, it is used as a biological tissue stain. As a solid,it is also known to be unstable and may explode. In thisway, it is similar to 2,4,6-trinitrotoluene (TNT). Draw thestructures of picric acid and TNT. Why is picric acid readily soluble in water, whereas TNT is not?arrow_forward
