The bond orders for N 2 2 + , N 2 − and N 2 2 − are to be determined. Also the species are to be ranked in the order of decreasing bond energy and decreasing bond length. Concept introduction: The molecular orbital diagram is a tool that is used to describe the chemical bonding formed between different molecules. It is used to predict the bond strength and the electronic transitions that a molecule can undergo. Bond order is the number of bonds that an atom can form with other atoms. Higher the bond order, more will be the stability of the molecule and vice-versa. Bond energy is the amount of heat that is needed to break the bonds between various atoms. It depends on bond order. Higher the bond order, more will be its bond energy and vice-versa. Bond length is the average distance between the centres of the atomic nuclei of the combining atoms. Its value is inversely proportional to bond order.

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
