The compound (1) converts to compound (5) through the mechanistic sequence under basic conditions and in the presence of MeO - as a catalyst. The resonance structure of compound (2) that is the greatest contributor is to be interpreted. Concept introduction: Resonance is the phenomenon of the interaction of lone pairs of electrons and pi electrons in a molecule. More resonance contributes to more stability of the molecule. The overall structure can be drawn as the sum of all resonating structures which is called a resonance hybrid.

Interpretation Introduction

Interpretation: The compound (1) converts to compound (5) through the mechanistic sequence under basic conditions and in the presence of MeO- as a catalyst. The missing lone pairs and curved arrows are to be interpreted for the given reaction mechanism.

Concept introduction: The chemical transformation can be shown by the arrow pushing method in which the curved arrows show the movement of electrons or protons. In a chemical reaction, the attack of reagent (electrophile or nucleophile), and loss of leaving group can easily be determined with the help of arrow pushing patterns.

You are trying to decide if there is a single reagent you can add that will make the following synthesis possible without any other major side products: xi 1. ☑ 2. H₂O хе i Draw the missing reagent X you think will make this synthesis work in the drawing area below. If there is no reagent that will make your desired product in good yield or without complications, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. There is no reagent that will make this synthesis work without complications. : ☐ S ☐

Predict the major products of this organic reaction: H OH 1. LiAlH4 2. H₂O ? Note: be sure you use dash and wedge bonds when necessary, for example to distinguish between major products with different stereochemistry. Click and drag to start drawing a structure. G C टे

For each reaction below, decide if the first stable organic product that forms in solution will create a new C-C bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. NH2 CI MgCl ? Will the first product that forms in this reaction create a new CC bond? Yes No MgBr ? Will the first product that forms in this reaction create a new CC bond? Yes No G टे
