- 17-60 1-Propanol can be prepared by the reduction of an aldehyde, but it cannot be prepared by the acid catalyzed hydration of an alkene. Explain why it cannot be prepared from an alkene.arrow_forwardWhen trans-2-chloro-1-cyclohexanol is treated with a base, cyclohexene oxide is the product. However, when cis-2-chloro-1-cyclohexanol is treated with a base, the product is cyclohexanone –arrow_forwardDraw a structure of 2-bromo-4-iodophenol :arrow_forward
- Draw the structure of each product from the reaction of benzene with 2-chloro-1-methylcyclohexane using AlCl 3 as the catalyst and Identify the major product.arrow_forwardAlkyl sulfonates undergo the same type of substitution reactions as alkyl halides and can also be prepared from alcohols. What advantage does the preparation of an alkyl sulfonate from an alcohol have over the preparation of an alkyl halide from an alcohol?arrow_forwardA 2-bromobutane react with methanol and form a enantiomeric pair of 2-methoxybutane. Draw the structures of the enntiomeric pairs of ethers.arrow_forward
- Alcohols undergo dehydration reactions in the presence of an acid catalyst. Which of the following compounds yields only a single alkene product upon dehydration?arrow_forwardWhen 2-chloropropane treated with NaOH and 1-chloropropane treated with NaOH separately produce two different functional groups. Provide both reactions and explain the two different functional groups produced.arrow_forwardDraw the products formed when alkene reacts with these reagents: (i) H2 in the presence of Pd catalyst, (ii) HCl.arrow_forward
- When trans-2-chloro-1-cyclohexanol is treated with a base, cyclohexene oxide is the product. However, when cis-2-chloro-1-cyclohexanol is treated with a base, the product is cyclohexanone. Why doesn’t the cis isomer yield the oxide?arrow_forwardThe acid-catalyzed dehydration of 2,3-dimethyl-3-pentanol yields three alkene products. What are the names of the three alkenes? Which of the three alkenes is the major product?arrow_forward1,3-Cyclohexadiene and 1,4-cyclohexadiene can be distinguished by reaction with ozone and then treatment with zinc. Draw the structures of the products produced by ozonolysis of the two compounds.arrow_forward
