Question

Draw the major product of this reaction. Ignore inorganic byproducts and the alcohol side product.

**Question 20 of 27** **Instruction:** Draw the major product of this reaction. Ignore inorganic byproducts and the alcohol side product. **Chemical Reaction:** The reaction involves the following steps: 1. Reagent: DIBAL-H (Diisobutylaluminum hydride), temperature: -78 °C 2. Reagent: H₂O **Structure:** The starting material is an ester, which is depicted in a linear structure with a carbonyl group (C=O) attached. The ester group is on the right end of the chain, shown as an O-CH₃ group connected to the carbonyl carbon. **Diagram Explanation:** A vertical arrow points from the ester to a dashed box labeled "Select to Draw," indicating where the reaction product should be drawn. - **Reagents and Conditions:** The use of DIBAL-H at low temperature suggests a partial reduction, typically resulting in the formation of an aldehyde from the ester group. Following treatment with water helps to complete the reduction process. **Outcome:** The likely major product is an aldehyde, where the ester group is reduced to a formyl group (CHO).
