    They have higher boiling and melting points compared to related hydrocarbons. Flammability reduces with increased chlorine substitution in hydrocarbons. [citation needed] Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage. [citation needed]
