- A compound of molecular formula C5H10O forms a yellow precipitate with 2,4-dinitrophenylhydrazine reagent and a yellow precipitate with reagents for the iodoform test. a) Draw the structural formulae b) Name the two (2) compounds that fit these tests.arrow_forwardUse the carboxylic acid and alcohol listed below to make an ester using a Fischer esterification. Draw a reaction scheme (like on the top of each page in the manual) to show which starting materials and reagents you would use, and name the product using proper nomenclature. Acetic acid (ethanoic acid) Ethanolarrow_forwardThiols or thiol (-SH) group is a better base than hydroxide (-OH) group in elimination reactions.arrow_forward
- The flavors and aromas of almost any fruit are primarily due to esters. In an experiment, an artificial fruit flavor is prepared using the Fischer esterification (reaction of an alcohol with a carboxylic acid in the presence of sulfuric acid catalyst). Why is it easier to remove excess carboxylic acid from the product than excess alcohol?arrow_forwardAcid (phosphiruc acid) is catalyzing this dehydration reaction(cyclphexanol to cyclohexene). What does that mean? How many equivalents of acid were needed for the reaction to proceed?arrow_forwardcomplete these reactions with reagents and intermediates.arrow_forward
- Aldehydes and ketones react with one molecule of an alcohol to form compounds called hemiacetals, in which there is one hydroxyl group and one ether-like group. Reaction of a hemiacetal with a second molecule of alcohol gives an acetal and a molecule of water. We study this reaction in Chapter 16. Draw structural formulas for the hemiacetal and acetal formed from these reagents. The stoichiometry of each reaction is given in the problem.arrow_forwardComplete the following reactions with the product or reagent as appropriatearrow_forwardComplete the following synthesis by filling in the missing reactants, reagents, and products.• Boxes with sharp corners are structures; rounded corners are reagents (may be written or drawn).• Reagent boxes may hold multiple reagents/steps.arrow_forward
- Draw the structure(s) of the organic product(s) of the Claisen condensation reaction between ethyl acetate and ethyl benzoate.arrow_forwarda)Step by step show the reaction of 1 mol of water from the 3,3-dimethyl-2-pentanol compound in acid-catalyzed medium.Name the main product formed. b)Indicate whether the resulting product shows the geometric isomer or not. c)Write the products formed when the product is ozonized and oxidized.arrow_forwardOn synthesis of esters via nucleophilic acyl substitution: Write the chemical equation involved in the reaction between the excess acid and NaHCO3. Given this, briefly explain why NaHCO3 is preferred over NaOH for the neutralization of excess acid. Also, explain how excess alcohol was eliminated from the crude product.arrow_forward
