Question

give reason an electrovalent compound e.g sodium chloride is a hard solid at ordinary temperature while covalent compounds are generally gases,liquids or soft solids at room temperature

Answer 1

Electrovalent compound are formed due to gain or loss of electrons between the elements.Hence they have strong intermolecular forces.Hence they are generally solid.

Answer 2

Answer:

The correct answer of this question is gain or loss of electrons between the elements results in the formation of electrovalent compounds.

Explanation:

Given - An electrovalent compound.

To Find - Give reason an electrovalent compound.

The electrostatic attraction between oppositely charged ions in a chemical molecule forms an ionic bond, also known as an electrovalent bond.

Gain or loss of electrons between the elements results in the formation of electrovalent compounds. They have significant intermolecular forces as a result. As a result, they're generally reliable. Because the oppositely charged ions in electrovalent compounds have a strong attraction, it takes a lot of energy to break the strong bonding force between them. As a result, they have high melting and boiling points.
