Organic Synthesis Reaction Pathways

This comprehensive flowchart details the various reaction pathways and transformations possible in organic synthesis. The diagram shows multiple routes for converting between different organic functional groups using specific reagents and conditions.

Definition: Organic synthesis refers to the intentional construction of organic molecules through chemical reactions.

Highlight: Key reaction types shown include esterification, oxidation, reduction, substitution, elimination, and addition reactions.

Example: The conversion of an alcohol to an ester requires a carboxylic acid and concentrated H₂SO4 under reflux conditions.

Vocabulary: Reflux refers to the process of boiling a reaction mixture while continuously condensing the vapor back into the reaction vessel.

The flowchart specifically details:

• Conversion of alcohols to esters using carboxylic acids and H₂SO4
• Oxidation reactions using acidified K₂Cr₂O7
• Hydrogenation of alkenes using nickel catalysts
• Catalytic cracking processes using Al₂O3 catalyst
• Free radical substitution reactions using UV light
• Nucleophilic substitution reactions with various nucleophiles
• Reduction reactions using LiAlH4

Quote: "Catalytic cracking requires Al₂O3 catalyst at 450°C for effective conversion"
