The more important resonance contributor from A and B is to be determined, and the reason behind this is to be explained. Concept introduction: The relative stabilities of resonance structures depend on the number of non-hydrogen atoms obeying the octet rule, the total number of bonds, the number of atoms bearing a formal charge, and charge stability. Higher the number of non-hydrogen atoms obeying the octet rule and higher the number of bonds, more stable is the structure. Lower the number of atoms with formal charge, more stable is the structure. A positive charge is more stable on a relatively less electronegative atom, and more stable near an electron donating group. An electron-withdrawing group destabilizes a positive charge. Closer the electron-withdrawing group to a positive charge more is the destabilization.

Question

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. ?

Chapter 6, Problem 6.30P

Interpretation Introduction

Interpretation:

The more important resonance contributor from A and B is to be determined, and the reason behind this is to be explained.

Concept introduction:

The relative stabilities of resonance structures depend on the number of non-hydrogen atoms obeying the octet rule, the total number of bonds, the number of atoms bearing a formal charge, and charge stability.

Higher the number of non-hydrogen atoms obeying the octet rule and higher the number of bonds, more stable is the structure. Lower the number of atoms with formal charge, more stable is the structure. A positive charge is more stable on a relatively less electronegative atom, and more stable near an electron donating group. An electron-withdrawing group destabilizes a positive charge. Closer the electron-withdrawing group to a positive charge more is the destabilization.

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.
