It should be determined that whether an organolithium compound or organosodium compound is more reactive. Concept Introduction: Nucleophilic reaction: electron rich nucleophiles attack the positive or partially positive charge of an atom and replace a leaving group is called Nucleophilic Substitution reaction. Electrophilic reaction: The aromatic substitution involves the attack on the electrophile by the π − e l e c t r o n of the aromatic ring and replacing one of the hydrogen molecules on the ring (or) respective species. Reactivity of organometallic compound : The reactivity of an organometallic compound depends on the polarity of the carbon-metal bond, the greater the polarity of the bond, the more reactive the compound is as a nucleophile, the polarity of the bond on the difference in electronegativity between the metal and carbon atom. Organolithium: Organolithium compounds are very strong base, therefore they will react immediately with any acid present in the reaction mixture, even with very week acids such as water and alcohol. Organosodium: Organosodium compound are less base when compare to the organo lithium compound because, organosodium compounds have less electronegative character.

Interpretation Introduction

Interpretation:

It should be determined that whether an organolithium compound or organosodium compound is more reactive.

Concept Introduction:

Nucleophilic reaction: electron rich nucleophiles attack the positive or partially positive charge of an atom and replace a leaving group is called Nucleophilic Substitution reaction.

Electrophilic reaction: The aromatic substitution involves the attack on the electrophile by the π−electron of the aromatic ring and replacing one of the hydrogen molecules on the ring (or) respective species.

Reactivity of organometallic compound: The reactivity of an organometallic compound depends on the polarity of the carbon-metal bond, the greater the polarity of the bond, the more reactive the compound is as a nucleophile, the polarity of the bond on the difference in electronegativity between the metal and carbon atom.

Organolithium: Organolithium compounds are very strong base, therefore they will react immediately with any acid present in the reaction mixture, even with very week acids such as water and alcohol.

Organosodium: Organosodium compound are less base when compare to the organo lithium compound because, organosodium compounds have less electronegative character.

How many signals do you expect in the H NMR spectrum for this molecule? Br Br Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in top molecule For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in bottom molecule
