It does not conduct electricity, as there are no electrons free to move and carry charge. It has a high melting point and boiling point as much energy is needed to break the many strong covalent bonds. ... Like diamond it has a high melting point.

Can simple molecular substances conduct electricity?

Simple molecules have no overall charge , or charged particles that can separate, so simple molecular substances cannot conduct electricity, even when liquid or dissolved in water. ... When simple molecular substances melt or boil, their weak intermolecular forces are overcome, not the strong covalent bonds.

Can methane conduct electricity?

Figure 6.2.

the atoms within each methane molecule are held together by strong covalent bonds. ... When molten, however, it can conduct electricity because its ions are able to move freely through the liquid (Figure 6.2.
