Sodium alkynides act as nucleophiles to undergo addition to aldehydes, giving secondary alcohols. Use this reaction to complete the synthesis of 1-octen-3-ol, used as the attractant in mosquito traps. Ignore any inorganic byprodcuts formed. Select to Draw 1. NaCCH 1. H3O+ Select to Draw OH

Draw the major product(s) for reaction of methyl pentanoate with: NaOH, H2O, heat; then H3o*

What is the major organic product obtained from the following reaction

1. NaOEt CO₂Et 2. H3O+ 3. heat Br H3C CO₂H CO2 H3C CO₂Et The malonic ester synthesis is a carbonyl alkylation reaction. It is used to prepare carboxylic acids from primary alkyl halides, lengthening the carbon chain by two atoms. Thus, the product can be visualized as being a "substituted acetic acid." The reaction consists of three steps: generation of the enolate anion followed by SN2 reaction with a primary alkyl halide, ester hydrolysis under acid conditions, and decarboxylation. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions 22 CX EtO₂C EtO₂C HOCH2CH3 HOCH2CH3 EtO₂C EtO₂C
