Organic Chemistry 8th Edition Chapter 19 Lecture Notes

These flashcards contain key vocabulary and definitions related to amines and their reactions as discussed in Chapter 19 of Organic Chemistry.

Amines

Organic compounds that contain a nitrogen atom bonded to hydrogen atoms, alkyl groups, or aryl groups, often acting as bases and nucleophiles.

Nucleophile

A species that donates an electron pair to form a chemical bond in a reaction.

Primary Amine

An amine with one carbon atom attached to the nitrogen atom.

Secondary Amine

An amine with two carbon atoms attached to the nitrogen atom.

Tertiary Amine

An amine with three carbon atoms attached to the nitrogen atom.

Nucleophilic Acyl Substitution Reaction

A reaction where a nucleophile attacks a carbonyl carbon, leading to a substitution at the carbonyl group.

Arenediazonium Salts

Highly reactive intermediates formed from aryl amines, useful in electrophilic aromatic substitution reactions.

Reductive Amination

A method for producing amines by reacting carbonyl compounds with amines in the presence of reducing agents.

Pyrrole

A five-membered aromatic heterocyclic compound with a nitrogen atom, known for its weak basicity.

Delocalization Energy

The energy associated with the resonance stability of a compound, often referring to the stability gained from electron delocalization.

Electrophilic Aromatic Substitution

A reaction where an electrophile replaces a hydrogen atom on an aromatic ring.

Pyridinium Ion

The conjugate acid formed when pyridine is protonated, making it a stronger acid than a typical ammonium ion.

Nucleophilic Aromatic Substitution

A reaction that occurs when a nucleophile attacks aromatic rings containing a leaving group, resulting in substitution.

Protonation

The addition of a proton (H⁺) to an atom, resulting in a cation.

Synthesis of Amino Acids

The process of creating amino acids from various starting materials, often involving transforming α-bromocarboxylic acids.

Purines

Nitrogen-containing compounds that form the basis of nucleotides in DNA and RNA, including adenine and guanine.

Porphyrin Ring System

A large, cyclic compound consisting of four linked pyrrole units, often complexing with metal ions such as iron.
