The enthalpy change of the given reaction is to be calculated. Concept introduction: Hess’s law states that the change in enthalpy of a reaction remains same whether the reaction takes place in one step or in multiple steps. Enthalpy change is independent of path of the reaction On adding the thermochemical equations, the value of enthalpy change is also added, which gives the enthalpy change of the net reaction. On reversing any equation, the sign of the enthalpy change value is changed to the opposite sign.

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
