Question

why do naphthalene and camphor sublime under normal condition of temperature and pressure

Answer 1

Naphthalene and camphor sublime under normal condition of temperature and pressure because they have very weak inter molecular forces.

- Naphthalene sublimes easily because it is made up of non- polar molecules which are held together only by weak van der Waals inter molecular forces.

- Similarly camphor overcomes its inter molecular forces easily at normal condition of temperature and pressure and undergoes sublimation.
