Hydration E.oxidationarrow_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_forward1. 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_forward

- From the scheme below, draw the structures of X and Y. These two compounds are the major products of their respective reaction. H2SO4 Y HCN heatarrow_forwardDESCRIPTION Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, ??=??. Alcohol can be synthesized by the reduction of aldehydes and ketones. The reduction of formaldehyde forms methanol while the other aldehydes produce primary alcohols. Moreover, secondary alcohols can be produced from the reduction of ketones. Aldehydes and ketones can be reduced by hydride agents’ reaction, catalytic hydrogenation and Grignard reagents reduction. Heterogeneous catalytic hydrogenation is the simplest method for the reduction of aldehydes and ketones into the corresponding alcohol, which is in huge demand. At present, metal catalysts are widely used in industry due to their high activity and low cost. TASK As a process engineer in a chemical manufacturing company, your team has been assigned to prepare the proposal on the process and suitable design of a reactor for catalytic hydrogenation of liquid aldehyde OR ketone into the desired alcohol based on the current…arrow_forwardDifferentiate primary, secondary, and tertiary alcohols.arrow_forward
