Hydrogen bonds are based on permanent dipoles that form when hydrogen comes in vicinity of a highly electronegative atom such as F, N or O. These bonds are long lasting and pretty strong. Vanderwall forces are based on temporary dipoles that form while the molecules are in the dtate of flux or motioRead more

See lessVanderwall forces are based on temporary dipoles that form while the molecules are in the dtate of flux or motion. Such forces are extremely short lived and weak.
So option C is correct
Correct answer is option C. @Arpita Samal described it best. Thank you. Some peripheral lines related to this topic: Van der waals forces, relatively weak electric forces that attract neutral molecules to one another in gases, in liquefied and solidified gases, and in almost all organic liquids andRead more
Correct answer is option C. Arpita Samal described it best. Thank you.
Some peripheral lines related to this topic:
- Van der waals forces, relatively weak electric forces that attract neutral molecules to one another in gases, in liquefied and solidified gases, and in almost all organic liquids and solids.
- Solids that are held together by van der waals forces characteristically have lower melting points and are softer than those held together by the stronger ionic, covalent, and metallic bonds.
- Unlike ionic or covalent bonds, van der waals bonds attractions do not result from a chemical electronic bond; they are comparatively weak and therefore more susceptible to disturbance. The van der waals force quickly vanishes at longer distances between interacting molecules.
