For the conversion from cis-2-butene to trans-2-butene isomer is whether exothermic or endothermic reaction has to be given. Concept Introduction: The effect on K C of raising temperature: For an endothermic reaction, the value of K C always will increases when increasing the temperature; at higher temperatures the reaction becomes more product-favoured for an endothermic reaction. For an exothermic reaction, the value of K C always will decreases when increasing the temperature; at higher temperatures the reaction becomes less product-favoured for an exothermic reaction.

Interpretation Introduction

Interpretation:

For the conversion from cis-2-butene to trans-2-butene isomer is whether exothermic or endothermic reaction has to be given.

Concept Introduction:

The effect on KC of raising temperature:

For an endothermic reaction, the value of KC always will increases when increasing the temperature; at higher temperatures the reaction becomes more product-favoured for an endothermic reaction.

For an exothermic reaction, the value of KC always will decreases when increasing the temperature; at higher temperatures the reaction becomes less product-favoured for an exothermic reaction.

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC 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. ?

Predicting As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule with a new C - C bond as its major product: H₂N O H 1. ? 2. H3O+ If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. 0 If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank. فا Explanation Check Click and drag to start drawing a structure.
