More stable contributing structure for each of the given structures is to be written, curved arrows are to be used which shows the transformation of the original Lewis formula to the new one and formal charges are to be specified. Concept introduction: The resonance structure with the greater number of covalent bonds contributes more to the resonance hybrid provided the octet rule is not exceeded for second-row elements. A Lewis structure can have more than one structure; they are called resonating structures. The movement of a pair of electrons is shown by curved arrows. the structure in which the negative charge is present on the most electronegative atom and the positive charge is present on the least electronegative element is known as the major resonance contributor. The species having the smallest separation of oppositely charged atoms is the major contributor.

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
