To explain, ∆G f 0 for the hydrogen halides become less negative with increasing atomic number , ∆G of HI is slightly positive and ∆S f 0 more positive with increasing atomic number. Concept introduction: To define as a enthalpy (∆H) and entropy (∆S), Enthalpy is the heat of reaction. A positive value means that the surroundings are doing work on the system, and a negative value means the opposite, that the system is doing work on the surroundings. To explain: ∆G f 0 for the hydrogen halides become less negative with increasing atomic number, ∆G of HI is slightly positive and ∆S f 0 more positive with increasing atomic number.

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
