The explanation for the reactive/non-reactive nature of lone pair in Nicotine has to be done. Concept Introduction: Lone pair: A lone pair is given by a pair of outer most electrons that are not shared with another atom, otherwise called as non bonding pair. These are generally found in the valence shell of atom and are identified by Lewis structure. Pairs of electrons are considered as lone pairs when two electrons are paired and are not participated in chemical bonding. The sum of number of lone pairs and number of bonding electrons equals the total number of outermost electrons around an atom. Delocalized lone pair: The lone pair that participates in resonance is called as delocalized lone pair. The presence of lone pair affects the geometry of the atom. Localized lone pair: The lone pair that doesn’t participate in the resonance is called localized lone pair. The lone pair is not allylic to π bond.

Interpretation Introduction

Interpretation:

The explanation for the reactive/non-reactive nature of lone pair in Nicotine has to be done.

Concept Introduction:

Lone pair:

A lone pair is given by a pair of outer most electrons that are not shared with another atom, otherwise called as non bonding pair. These are generally found in the valence shell of atom and are identified by Lewis structure. Pairs of electrons are considered as lone pairs when two electrons are paired and are not participated in chemical bonding. The sum of number of lone pairs and number of bonding electrons equals the total number of outermost electrons around an atom.

Delocalized lone pair:

The lone pair that participates in resonance is called as delocalized lone pair. The presence of lone pair affects the geometry of the atom.

Localized lone pair:

The lone pair that doesn’t participate in the resonance is called localized lone pair. The lone pair is not allylic to π bond.

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
