Which type of compound has a high melting point and can conduct electricity when melted or dissolved in water?

Which type of compound has a high melting point and can conduct electricity when melted or dissolved in water?

Ionic compounds
Ionic compounds have ionic bonds between ions of opposite charges. Ionic compounds are usually brittle, have high melting points, dissolve in water, and often conduct an electric current in solution. Covalent compounds have covalent bonds and consist of particles called molecules.

What is an example of a covalent compound with a high melting point and boiling point?

These covalent bonds are very strong. They also tend to be very hard with high melting points which are different from most of the covalent compounds. The example of this kind of covalent compounds includes diamond and graphite of carbon atom network.

What are the melting and boiling points of covalent compounds?

Covalent bonds between atoms are quite strong, but attractions between molecules/compounds, or intermolecular forces, can be relatively weak. Covalent compounds generally have low boiling and melting points, and are found in all three physical states at room temperature.

What conducts electricity and has a high melting point?

Ionic crystals
Ionic crystals are hard and brittle and have high melting points. Ionic compounds do not conduct electricity as solids, but do conduct electricity when molten or in aqueous solution.

Do covalent compounds have high melting points?

All covalent network structures have very high melting points and boiling points because many strong covalent bonds need to be broken. They are all hard, and do not conduct electricity because there are no free charges that can move.

Which of the following covalent substances have high melting point?

Due to strong covalent bonding within the layers, graphite has a very high melting point, as expected for a covalent solid (it actually sublimes at about 3915°C).

What bond has a high melting point?

ionic bonding
Short answer: Compounds with ionic bonding have higher melting points than those with covalent bonding. Intermolecular forces determine the melting points of compounds.

Why covalent bond has low melting and boiling point?

Covalent compounds are held together by weak intermolecular forces. It is because of such weaker forces, which fails to make the compound bind tightly. Since lower heat (energy) is capable of breaking these weak intermolecular forces, therefore the melting and boiling points of covalent compounds is low.

What is the boiling point of covalent compounds?

Explanation

Substance	Melting point	Boiling point
O 2	-218°C	-183°C
H 2O	0°C	100°C

Do ionic compounds have high melting points?

Ionic compounds are held together by electrostatic forces between the oppositely charged ions . As the ionic lattice contains such a large number of ions, a lot of energy is needed to overcome this ionic bonding so ionic compounds have high melting and boiling points.

What chemical compound has the highest melting point?

The chemical element with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); this property makes tungsten excellent for use as electrical filaments in incandescent lamps.

How are the melting and boiling points of covalent compounds explained?

Explaining the melting and boiling points of covalent compounds. Covalent compounds are composed of molecules. The bonding in these covalent compounds consists of strong covalent bonds between the atoms in the molecule. weak forces of attraction between the molecules. An example is shown in Figure.

Can a covalent compound conduct electricity in a solid state?

They can conduct electricity in the molten and aqueous states. Covalent compounds are volatile and have low melting and boiling points. They are usually insoluble in water but soluble in organic solvents. They cannot conduct electricity in the solid and liquid states.

Why are all covalent bonds soluble in water?

They are generally soluble in water. All covalent network structures have very high melting points and boiling points because many strong covalent bonds need to be broken. They are all hard, and do not conduct electricity because there are no free charges that can move.

Which is an ionic compound and which is a covalent compound?

Naphthalene, as a covalent compound, is made up of covalent molecules only. Hence, it cannot conduct electricity in the solid and liquid states. Ionic compounds are non-volatile and have high melting and boiling points. They are usually soluble in water but insoluble in organic solvents.
