  1. Naphthalene undergoes sublimation, the change from a solid directly into a gas without going through the liquid phase.
    Compounds with relatively high vapor pressures have low intermolecular forces and undergo sublimation. Even water ice will undergo sublimation.
    Naphthalene consists of two benzene rings bonded together. It is nonpolar, and has low intermolecular forces, which accounts for its high volatility and ease of sublimation.
