How are ionic and covalent compounds different in terms of melting and boiling point and electrical conductivity and hardness and brittleness?

Answer 1

Ionic compounds generally have higher melting and boiling points.

Answer 2

Ionic compounds have higher melting and boiling points compared to covalent compounds due to the strong electrostatic forces between ions in ionic compounds. Ionic compounds can conduct electricity when dissolved in water or in a molten state, while covalent compounds generally do not conduct electricity. Ionic compounds are usually hard and brittle, while covalent compounds can be soft and flexible.

Answer 3

The electrostatic attraction in an ionic bond is very strong hence a lot of heat energy is required to break it down and thus explaining why ionic bonds have high melting and boiling points. However,In covalent bonds, the intermolecular forces are very weak and is easily broken,hence lesser heat is required and thus covalent bonds have lower melting and boiling points.

Answer 4

Ionic compounds are the strongest of all, breaking the bonds takes a lot of energy, their boiling and melting points are much higher. Ionic compounds do not conduct electricity at all, except one that i can't remember

lier ionic compounds conduct electricity.

They conduct electricity when they are in solution or in a molten state

Answer 5

Molecular compounds have lower melting points, lower boiling points and lower conductivity than ionic. This is because the ionic compounds are giant lattice compounds hef together with electrostatic forces which when dissolved or mlten have free ions that can conduct electricity. Molecular compounds in th eliquid and solid are held together with weak intermolecuar forces, (van der Waals) and when molten or dissolved are uncharged so that they do not conduct.

Answer 6

As a generalization, the melting and boiling points of ionic compounds are substantially higher than the corresponding characteristics of covalent compounds. However, there are some ionic compounds with lower melting points than many covalent compound. Some substituted tetra-ammonium salts in particular are liquid at room temperature. There are also some covalent compounds such as diamond with higher melting points than most ionic compounds.

Answer 8

In general, ionic compounds have higher conductivity, melting points, and boiling points than molecular compounds.

Let me again stress that in general.

Answer 9

They all have lower points than those of ionic compounds

Answer 10

Ionic compounds have higher melting and boiling points than moleculars compounds. They do not vaporize as easy,
