Question

Which is weakest ? a)Ionic bond. b)Covalent bond. c)Metallic bond. d)Vander waal forces​

Answer 1

Answer:

The van der Waals force quickly vanishes at longer distances between interacting molecules. Clearly, the correct answer is (D). Note: Do not confuse Van der Waal forces with ion-dipole force or dipole-dipole force. Dipole-dipole forces occur between molecules with permanent dipoles (i.e., polar molecules).
