Haloalkanes definition
Haloalkanes definition
Alkanes with H atoms replaced by halogen atoms (F, Cl, Br, I)
General formula of haloalkanes
General formula of haloalkanes
where X is a halogen
Halogen prefixes in naming
Halogen prefixes in naming
Fluoro-, chloro-, bromo-, iodo-
Why C-halogen bond is polar
Why C-halogen bond is polar
Halogen more electronegative than C, creates and
Effect of halogen size on boiling point
Effect of halogen size on boiling point
Larger halogen = higher bp (I > Br > Cl > F)
Effect of longer C-chain on H₂O solubility
Effect of longer C-chain on H₂O solubility
Decreases - non-polar hydrocarbon part becomes dominant
Why haloalkanes more reactive than alkanes
Why haloalkanes more reactive than alkanes
Polar C-X bond makes C susceptible to nucleophile attack
Product when haloalkane reacts with OH⁻
Product when haloalkane reacts with OH⁻
Alcohol (halogen replaced by -OH group)
How CFCs damage ozone layer
How CFCs damage ozone layer
UV breaks C-Cl bond, releasing Cl radicals that destroy O₃
Why one Cl radical destroys many O₃ molecules
Why one Cl radical destroys many O₃ molecules
Cl acts as catalyst - regenerated after each reaction cycle
