Ionic compounds conduct electricity when dissolved in water, because the dissociated ions can carry charge through the solution. Molecular compounds don’t dissociate into ions and so don’t conduct electricity in solution.
Why are molecular compounds poor conductors of electricity than Ionic compounds?
Covalent compounds are formed on the basis of sharing electrons. When the electrons are shared within the bonds, there is no electrons available to conduct electricity – hence why covalent compounds are generally poor conductors of electricity.
Why are some molecular compounds good conductors of electricity?
Covalent molecular substances which are acidic or basic react with water producing free mobile atoms. The resulting ions are able to move freely throughout the solution carrying charge and hence conducting an electric current.
Are Ionic compounds better conductors?
Yes ;Ionic compounds are good conductors of electricity because ionic compounds dissociate into ions in molten or aqueous solution and these ions are responsible for the conduction …

Why are ionic compounds different from molecular compounds?
Molecular compounds are pure substances formed when atoms are linked together by sharing of electrons while ionic compounds are formed due to the transfer of electrons.Molecular compounds are formed between two non-metals while ionic compounds are formed between metals and non-metals.
Why are simple molecular compounds poor electrical conductors?
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.
Are ionic compounds good conductors of electricity at room temperature?
At room temperature, ionic compounds are solids and do not have any free electrons, hence they conduct electricity in molten state. So, they are not good conductors of electricity at room temperature.
Why does an ionic compound conduct electricity as a liquid?
Ionic compounds do not conduct electricity in solid state as the ions are not free to move. Ionic compounds conduct as liquids or when in solution as the ions are free to move.
Are molecular compounds good conductors?
Since molecular compounds are composed of neutral molecules, their electrical conductivity is generally quite poor, whether in the solid or liquid state. In solid form, an ionic compound is not electrically conductive because its ions are unable to flow (“electricity” is the flow of charged particles).
How does the structure of ionic compounds affect their ability to conduct electricity?
How does an ionic compound’s structure affect its ability to conduct electricity? Tightly bound valence electrons restrict free movement of electrons that is necessary for electrical conduction, as in metals.
Why are ionic bonds good insulators?
Ionic ‘solids’ are insulators because of the absence of free ions that are needed for the flow of electricity through them. Pure ionic solids are an aggregate of positively and negatively charged ions help by strong electrostatic forces in a rigid crystal lattice.
Why are metals better at conducting heat compared to ionic compounds?
Why do metals conduct heat so well? The electrons in metal are delocalised electrons and are free moving electrons so when they gain energy (heat) they vibrate more quickly and can move around, this means that they can pass on the energy more quickly.
What is a good conductor of electricity?
Most metals are considered to be good conductors of electrical current. Copper is just one of the more popular materials that is used for conductors. Other materials that are sometimes used as conductors are silver, gold, and aluminum.
What does good conductor of electricity mean?
If you have to define the meaning of electrical conductors in the simplest way, they are materials that allow electricity to flow through them easily. If we compare two types of material and the first one allows better flow of electricity through it, then that material is said to be a good conductor of electricity.
Which is a difference between molecular compounds and ionic compounds quizlet?
What is the difference between an ionic compound and a molecular compound? In ionic compounds the atoms (or group of atoms) exist as ions and are held together by electrostatic forces. In molecular compounds the atoms are held together by covalent bonds.
How can you tell the difference between ionic and molecular compounds?
As a general rule of thumb, compounds that involve a metal binding with either a non-metal or a semi-metal will display ionic bonding. Compounds that are composed of only non-metals or semi-metals with non-metals will display covalent bonding and will be classified as molecular compounds.
Why are materials with covalent and ionic bonds considered poor conductors of heat and electricity compared to metals?
because covalent bonds are formed by sharing of electrons..they don’t have a free electron that is required for electricity transfer(electricity is the flow of free electrons!) thus they re bad conductors.. but ionic compounds are good conductor because of the same reason…
Are the forces between the ions in an ionic compound strong or weak?
electrostatic forces
Since the electrostatic forces of attraction between oppositely charged ions are strong, their melting and boiling points are high.
What has poor electrical conductors in all phases?
(covalent/ionic) compounds are gases, liquids, or solids (made of molecules). They have low melting and boiling points. They are poor electrical conductors in all phases. Many are soluble in nonpolar liquids but not in water.
Why are ionic compounds good conductor of heat?
Ionic compounds don’t conduct electricity very well because the charge carriers can’t move through the crystal. They can conduct heat because the kinetic energy itself is the “heat carrier” – it can be transferred without moving ions too far from their mean positions.
