Which is NOT a typical property of organochlorines?

• A. Stability
• B. Lipophilicity
• C. Planarity
• D. High vapor pressure

Answer: (D)

Organochlorines are known for environmental persistence due to strong carbon–chlorine bonds that resist degradation, giving them high chemical stability. Their chlorine-containing, often nonpolar skeleton makes them highly lipophilic, so they readily partition into fats and bioaccumulate in the food chain. Planarity is not guaranteed across all organochlorines; some structures can be planar while others are twisted, so it’s not a universal defining trait. High vapor pressure would mean they evaporate easily, but these compounds are typically less volatile because of their heavier molecular weight and strong intermolecular forces, so high vapor pressure is not a typical property.
