By: Adeel, Sankeeth, and Sen Alkanes and Aromatics
Types of Reactions Alkanes Aromatics Substitution Reaction Halogenation (Halogen) Nitration (HNO3) Alkylation (Alkyl Halides) • Substitution Reactions • UV or heat as catalyst • Product formed is always halogenated alkane • Combustion Reaction
Alkane Reactions Combustion Reaction: Substitution Reaction:
Aromatic Reactions Nitration: Alkylation: Halogenation:
Practical and Industrial Uses Alkanes Aromatics Earlier Uses: After shave lotion Industrial solvent for degreasing metals Current Uses: Intermediate to make other chemicals (eg. Ethylbenzene, cyclohexane) Small amounts used to make rubbers, lubricants, dyes, detergents, drugs, and explosives. • Used as fuels • 1-4C: heating and cooking purposes • 5-8C: serve as fuels for internal combustion engines • 9-16C: diesel and aviation fuel • 16+C: lubricating oil and fuel oil
Environmental Impact AROMATICS • Air Pollution • Water,Marine Life • Plants, Roots, Crops • Photochemical Smog ALKANES • Air Pollution • Greenhouse Gas Effect • Acidic Rain • Plants • Fish • Wildlife • Structural Damage
Summary of Alkanes • 2 Reaction types : Combustion and Substitution • Industrial use : Fuels • Heating and cooking • Internal combustion engines fuel • Diesel and aviation • Lubricating oil and fuel oil • Environmental Impact • Air Pollution • Greenhouse Gas Effect • Acidic Rain (Fish, Wildlife, Plants, Structural Damage)
Summary of Aromatics • 3 Reaction types : Nitration, Alkylation, Halogenation • Industrial Use • After shave lotion • Degreasing metal solvent • Rubbers, explosives, detergents, lubricants, dyes, and drugs. • Chemical creation intermediate (cyclohexane). • Environmental Impact • Air pollution • Photochemical Smog • Plants, Roots, Crops • Water, Marine Life
