Interpretation Introduction

(a)

Interpretation: The energy diagram for the concerted reaction with ΔH°=80kJ/mol and Ea=16kJ/mol is to be drawn. The axes, the starting material, product, transition state, ΔH°, and Ea are to be labeled in the energy diagram.

Concept introduction: The reactions in which product are formed by the breaking and making of bonds in a single step are known as concerted reactions. The activation energy (Ea) aids in determining the rate of the chemical reactions. The small value of Ea exhibits that less energy is required to convert the reactants into products. It increases the rate of reaction. The change in enthalpy (ΔH°) indicates the relative position of starting material or product in the chemical reaction. The highest point in the energy diagram along the reaction coordinates is referred as transition energy. The energy difference between starting material or product is expressed by ΔH°.

Interpretation Introduction

(b)

Interpretation: The energy diagram for a two-step reaction, ABC, where the relative energy of these compounds is ACB, and the conversion of AB is rate-determining step is to be drawn.

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
