Do covalent networks have LDF's or not? Or is graphite the only covalent network that has LDF's.
All molecules have London dispersion forces , as they all have electrons. Even if bonded covalent or ionic, even if polar or non polar …..The only difference is the strength of the LDF, so more electrons (essentially atomic number) = higher LDF.

More branching = less efficient LDF.

Hope it helps :smile:

Thank you. That makes sense. Could you explain the answer for this please…

5. An element contains covalent bonding and London dispersion forces. The element could be
A boron
B neon
C sodium
D sulfur.

What are you thinking so far? Which types of elements commonly form covalent bonds, and can exist (as an element) as molecules?

Graphite is the only covalent network that has LDFs (Lattice Defects, or Dislocations). Other covalent networks may have other types of defects, but not LDFs.
