Halogenated organic compounds

Organic molecules with halogens bonded to carbon atoms

Four main halogens in these compounds

F\text{F}, Cl\text{Cl}, Br\text{Br}, I\text{I}

Three uses of haloalkanes

Refrigerants, firefighting agents, polymer production

Environmental impact of haloalkanes

Ozone layer depletion via atmospheric reactions

IUPAC priority when numbering chains

Double/triple bonds get lowest possible numbers

Naming: F, Cl, Br, I become

fluoro, chloro, bromo, iodo

Prefix for two identical halogens

di-

Prefix for three identical halogens

tri-

Arranging substituents in IUPAC names

Alphabetically, ignoring prefixes (di-, tri-, tetra-)

Tetrahedral bond angle around carbon

Approximately 109.5°109.5°
