iodine is a non- polar molecular solid iodine moleculas are held together by london force or dispersion force , this is soft and non – conductor fo electricity . Water is a hydrogen bonded molecular solid in which H and O are held together by to non – ionic nature , they are not electrical conductor.
What materials are not electrical conductors?
Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.
Which of the following solids is not an electrical conductor magnesium?
Hence, Option “C” is the correct answer.
Do all solids conduct electricity?
Solid metals conduct electricity and heat, while ionic solids do not. Many solids are opaque, but some are transparent. Some dissolve in water, but some do not.
Is TiO solid an electrical conductor?
(II) TiO(s): TiO(s) is an ionic solid and is an insulator in solid state but is a conductor in molten state and in aqueous solutions. (III) I2(s): I2(s) is a non-polar molecular solid and it is an insulator. Hence, does not conduct electricity.
What are 5 insulators?
What are 10 examples of conductors?

Is Quartz a good electrical conductor?
Quartz crystal is the most widely used crystal when it comes to conducting electricity. It’s resistance to wear and heat, added to its ability to regulate electricity, makes it a highly valuable substance for technology engineers.
Is MgO a good conductor of electricity?
MgO is prized as a refractory material, i.e. a solid that is physically and chemically stable at high temperatures. It has two useful attributes: high thermal conductivity and low electrical conductivity.
Is graphite a good conductor of electricity?
In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity.
