Most organic materials are nonconductors of electricity because they lack free electrons or mobile charge carriers that can easily move through the material to conduct electricity. The molecular structures of organic materials typically do not have delocalized electron pathways, unlike metals or semiconductors, which are good conductors of electricity.
Most nonconductors have covalent bonds. One thing that complicates matters is that some materials with purely covalent bonds do conduct electricity at least to some degree.
Most non-metals are in fact considered to be non-conductors. Some non-metals however do have the ability to conduct heat and electricity.
Generally not.

Ruby is a non-conductor of electricity because it is an insulator. Ruby is a form of corundum, which is a mineral composed of aluminum oxide. It does not conduct electricity due to its crystalline structure and lack of free flowing electrons.

Insulators
Materials that do not allow electricity to flow through them are called insulators. These materials have high electrical resistance, which prevents the flow of electric current. Common examples of insulators include rubber, glass, and plastic.
Almost everything is a good conductor of sound, but a conductor of heat and electricity are usually only metals. A nonmetal can be an insulator, or something that doesn't conduct things, for heat and electricity.
Most covalent compounds have relatively low melting and boiling points, as they are held together by weak intermolecular forces. They are usually insoluble in water but soluble in nonpolar solvents. Covalent compounds tend to be nonconductors of electricity in their solid form.
Halogens have 7 electrons in last orbit. They disparately want one electron to fill there last orbit. So they will simply hold the electrons tightly and as you know, for electricity to flow there should be free electrons. They will not give electrons so easily as metals do, who wants to get rid of extra electron/electrons to fill there outer orbit. If very high voltage is applied halogens may be forced to conduct electricity and Nobel gases will give up before halogens, when forced to conduct electricity.
