    Identify Unknown Compound with Iodoform Test and Baeyer Reagent

    An unknown compound burned with a yellow, nonsmoky flame and was found to be insoluble in 5% sodium hydroxide solution but soluble in concentrated sulfuric acid. Measurement of its boiling point gave a range of 130-131 degrees C. Combustion analysis gave a molecular formula of C5H8O. It was found to give a semicarbazone with

    Primary Alcohols Oxidizing to Aldehydes and Carboxylic Acids

    Primary alcohols can be oxidized to aldehydes and carboxylic acids. Often it is difficult to stop at the aldehyde oxidation state. One method frequently used to accomplish this, for those that boil below about 100 degrees C, is to remove the product from the reaction mixture as it is formed. This method is based on the fact t

    In the preparation of amides, acid chlorides or anhydrides may be used to react with the selected amine. It is known that acid chlorides are more reactive than the corresponding anhydrides in this type of nucleophilic acyl substitution reaction. Offer a reasonable explanation for this observation.
