Halogenoalkanes

• Halogenoalkanes are more reactive than alkanes due to polar bonds.
• Polar bonds in halogenoalkanes enable substitution and elimination reactions.
• Key mechanisms include nucleophilic substitution with hydroxide ions, chloride ions, and ammonia.
• Halogenoalkanes can undergo substitution and elimination reactions with potassium hydroxide to form alcohols and alkenes.
• Chlorine radicals can act as catalysts for decomposing ozone.
