Question 8

Chemical Bonding

The forces holding naphthalene crystals together can be overcome when naphthalene is heated to a temperature of 354 K resulting in the crystals melting. These forces are known as

  1. A.coulombic
  2. B.ionic
  3. C.covalent
  4. D.Van der Waals
Show the answer and explanation

Answer: D (Van der Waals)

Explanation

Naphthalene is a molecular solid. Its molecules are held together by weak van der Waals forces, which is why it melts at a low temperature.
