The reaction will be spontaneous, nonspontaneous, or temperature dependent if Δ H is negative and Δ S is positive has to be predicted with reasoning. Concept Introduction: Reaction can be said to be spontaneous, nonspontaneous or temperature dependent by considering the free energy change. Free energy is symbolized as Δ G . The equation for free energy can be given as, Δ G = Δ H − T Δ S If the value of Δ G is negative, then the reaction will be spontaneous and if the value of Δ G is positive, then the reaction will be nonspontaneous. Apart from this another condition is that if both Δ H and Δ S are either positive or negative, the reaction will be temperature dependent.

Interpretation Introduction

Interpretation:

The reaction will be spontaneous, nonspontaneous, or temperature dependent if ΔH is negative and ΔS is positive has to be predicted with reasoning.

Concept Introduction:

Reaction can be said to be spontaneous, nonspontaneous or temperature dependent by considering the free energy change. Free energy is symbolized as ΔG. The equation for free energy can be given as,

ΔG=ΔH−TΔS

If the value of ΔG is negative, then the reaction will be spontaneous and if the value of ΔG is positive, then the reaction will be nonspontaneous. Apart from this another condition is that if both ΔH and ΔS are either positive or negative, the reaction will be temperature dependent.

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
