Interpretation:
The product that results when citronellal is treated with excess H2 in the presence of a Pd catalyst should be determined.

Reaction of 4-chlorobutanal with Imole of hydrogen 5. Reaction of two 2-pentanethiol HgC CH3 6. Oxidation of H3C HO, 2,4- dime thyl bwtanol 7. Oxidation of H. 9. Hydrogenation of SH 10. Reaction with chloromethane ofarrow_forwardDraw the structure(s) of the organic product(s) of the Claisen condensation reaction between ethyl acetate and ethyl benzoate.arrow_forwardWhat is the balanced reaction of 1,2-diphenyl-1,2-ethanediol (hydrobenzoin) reaction with acetone to form a crystalline acetonide (a ketal)?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_forwardAccount for the fact that treating propenoic acid (acrylic acid) with HCl gives only 3-chloropropanoic acid.arrow_forwardAldehydes 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_forward

- Draw a structural formula for the intermediate that forms in the acid catalyzed reaction between methanol and 2-ethylbenzoic acid. Give the IUPAC names of the two reagents that would react in a Fischer esterification reaction to produce the intermediate shown. 0-H CH3CH2C- -OCH3 OH reagent 1 = reagent 2 Draw a structural formula for the missing intermediate in the reaction below. H₂SO4 H₂SO4 + CH3OH ? CH3CH2CH2CH2CH2COH + H₂O CH3CH2CH2CH2CH2COCH3arrow_forwardIn the synthesis of dibenzalacetone, what is the purpose of adding ethanol? It increases the acidity of the alpha hydrogen. It serves as an alternative to acetone as reactant. It strengthen the basicity of NaOH It increases the solubility of benzaldehyde and acetone.arrow_forwardUsing chemical structures draw the complete chemical reaction of Acetone with benzaldehyde under basic conditions, provide both the major and minor products.arrow_forward
