- 2. An unknown organic compound has the molecular formula C4H&O. It resists oxidation and it can be reduced with H2 to form an alcohol. Draw the structure for the compound and write equations for the reactions described. Name the reactant and product. 3. Draw the structures for 2,3-dimethylhexanal undergoing the following reactions: Oxidation Reduction with H2 Draw the structures for 2-methyl-3-hexanol undergoing the following reactions: Intramolecular dehydration Oxidation Rank the following from lowest to highest boiling point. Explain your ranking. Butanal, 1-butanol, butane Both ethane and ethanol contain 2 carbon atoms. Ethane is a gas at room temperature and is insoluble in water, whereas ethanol is a liquid at room temperature and is very soluble. Explain the reasons for the differences in the properties of these compounds.arrow_forward2. Using structures, write the chemical reaction for the dehydration of cyclohexanol to produce cyclohexene. Indicate any important reagents and reaction conditions (temperature, use of catalyst).arrow_forward3. Predict the products of the following reactions. Draw out the condensed structural formulas for the reactants and the products. Name the products (organic compounds only.) a) Monobromination of 2,2-dimethylpropane b) Hydrogenation of 2,3-dimethylcylcopentene ntadione Hydrohalogenation of 2,4-dimethyl-2-hexene with HBr d) Halogenation of 3-methyl-1-butyne with Cl2 (1:2 ratio) e) Hydration of 1,3-dimethylcylobutene f) Alkylation of benzene with 2-chlorobutanearrow_forward
- 1. Most margarines have been hydrogenated to maintain a soft, homogeneous mixture. While the product is easy to spread, this has made the product an unhealthy choice. A hydrogenation reaction is used to convert an alkene to an alkane. a carboxylic acid to an aldehyde. an alkene to a ketone an aromatic hydrocarbon to a linear hydrocarbonarrow_forwardHow does the structure of an alcohol differ from an ether? Describe how an aldehyde differs in structure from a ketone. Thiols are compounds which resemble alcohols, except that the oxygen atom is replaced by a sulfur atom. Draw the analogous thiol for the four carbon alcohol in Table 1. Describe the structural difference between carboxylic acids and esters. Are ethers polar molecules? Would you expect ethers to have higher or lower boiling points than alkanes (circle one)? Explain. Pentane (an alkane) has a boiling point of 36 °C. Does the data agree with your prediction? explain why this could be the casearrow_forwardb) Ho わ-fャコーfつ Koc 5. Complete the following oxidation reactions for alcohols.
