The substances that can form hydrogen gas on reaction with acids should be identified. Concept Introduction: Reaction with acids may include several variations such as neutralization. Neutralization reaction involves concentration of an acid and base that generates a salt from the cation and anion substrates along with removal of water. For instance reaction among NaOH and HCl is as follows: NaOH + HCl → NaCl + H 2 O Thus reaction between basic carbonate and acid to form salt and water is neutralization. Similarly, with alkaline hydrogen carbonates and acids salt and carbon dioxide is released. Metal hydroxide treatment with acids such as HCl , sulfuric acid or nitric acid from corresponding salts by neutralization along with release of water. Release of hydrogen gas can be used to detect and identify nature of reactant.

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.
