Question

Compounds with high melting points have _____

Answer 1

Compounds with high melting points have $\boxed{{\text{C}}{\text{. ionic bonds}}}$.

Further Explanation:

The attraction between different atoms, molecules and ions is known as a chemical bond. Such bonds are responsible for the formation of chemical compounds.

Ionic bond

It is formed by the interaction of a metal with a non-metal. Metals are electropositive in nature so they have the tendency to lose electrons whereas non-metals tend to gain electrons due to their high electronegativity. Metal atoms form cations by loss of electrons and non-metals become anions with the gain of electrons.

Covalent bond

It is formed by the mutual sharing of electrons between the bonded atoms. It is also known as a molecular bond. Such bonds usually exist between two or more non-metals.

Metallic bonds

These are formed between metal atoms and metallic solids are produced. These are good conductors of electricity due to the presence of delocalized electrons. Copper, gold, zinc are examples of metallic solids.

An ionic bond is the strongest bond, followed by metallic bond and covalent bond is the weakest among the three given bonds. A large amount of energy is required to break ionic bonds as compared to the other two bonds so compounds with ionic bonds have high melting points. Therefore option C is correct.

Answer 2

Answer:

C) Ionic bonds

Explanation:

The ionic bonds are the strongest bond, it occurs when a metal donates electrons and a nonmetal gain these electrons. They'll be together by electrostatic force.

Metallic bonds it the second strongest bond, it occurs between metals, which loses electrons. It's an electrostatic force, but weaker than the ionic compound because it occurs between the cation and the electron.

Covalent bonds are the weakest bond. It happens between metals and nonmetals, or nonmetals and hydrogen or between atoms of hydrogen. The force that joins the atoms depends on the polarity of the molecule. Polar molecules have dipole forces, nonpolar molecules, induced dipole forces. Also, hydrogen makes special dipole forces with nitrogen, oxygen, and fluorine, called hydrogen bond.

As the stronger is the force, as difficult it will be to break it. So, ionic bonds will demand more energy to become gas, and have high melting points.
