![]() ![]() Be familiar with basic conversions such as : There are various types of reactions to change functional group. ![]() Reactions to change the Functional groups ![]() This reaction can be used to reduce one carbon atom from carboxylic acids and their salts.Ĭarboxylation, Carbonylation, Decarboxylation reaction and Decarbonylation reaction Decarboxylation reaction(reaction with NaOH+CaO): ( Note: Ethanoic acid can be converted to ethanamide by direct treating with NH 3 also)Ģ. You can find this portion easily on the given conversion chart. Q) How would you prepare methanol from ethanoic acid? Then convert the amine to required organic compound as asked in the question. Most common methods for stepping down the carbon chain are mentioned below:Ĭonvert the given compound to an amide then let it undergo Hoffmann Bromamide reaction to form amine having one carbon less than that in amide. Stepping down the C- chain means that the product has shorter carbon chain than that of reactant. Aldol condensation reaction to form β-hydroxy aldehyde or ketone. Reaction of HCN with aldehyde to form α-hydroxy acid.ħ. Use this reaction to make product having double number of carbon atoms than in reactant.Ħ. You can find this portion in the given conversion chart, so you can do this type of conversions also using conversion chart. Most common methods for stepping up the carbon chain are mentioned below:Ĭonvert the given compound to an alkyl halide then to a cyanide then to the required organic compound as asked in the question. Stepping up the C- chain means that the product has longer carbon chain than that of reactant. Stepping up and down the carbon chain(series) Reactions that convert functional groups from one to another. Reactions that involve stepping up and down the carbon chain.Ģ. Search this portion of reactions on the given conversion chart, you can get easily.Īn organic conversion typically involves two types of transformationsġ. How would you convert methane to ethanoic acid ? Look at the final compound you want to obtain (final product) and initial compound and see the various intermediate compounds formed between reactant and product step by step.
