Diazonium Salts & Nucleophilic Aromatic Substitution: Crash Course Organic Chemistry

The video explores the chemistry behind food additives like sodium nitrite, which enhances color and prevents bacterial growth. It delves into the reactions of nitrous acid with amines, leading to the formation of diazonium salts, and discusses their instability and potential applications. The video also covers the stability of aryl diazonium salts and their use in creating azo dyes, which are common in food coloring. It contrasts electrophilic and nucleophilic aromatic substitution reactions, providing examples and synthesis problems to illustrate these concepts.

Discuss the stability differences between alkyl and aryl diazonium salts.

What steps are involved in synthesizing meta-dichlorobenzene from benzene?

What is the mechanism of diazo coupling in the formation of azo dyes?

How do electrophilic and nucleophilic aromatic substitutions differ?
