Covalent compounds have a.have high melting and boiling point b are most souble in water c.are formed between two atoms of metals and non metals. d.are formed by the sharing of electrons in the bonding atoms.?

Question

Answer

Option d.....A covalent compound is made when two or more nonmetal atoms bondby sharing valence electrons. The shared valence electrons between two nonmetal atoms is called a covalent bond. .

Answer

Covalent compounds are formed by the sharing of electrons in the bonding atoms.

This is so because in the atoms of the covalent compounds, there are four valence electrons . The atom of covalent compound is neither able to lose its four valence electrons nor to gain any other atom's four valence electrons due to energy considerations. Therefore in order to obtain inert gas electronic configuration covalent compounds share electrons.

Answer

Covalent compounds have:
Covalent compounds are formed when atoms share electrons to form chemical bonds. These compounds have several distinctive properties:

High melting and boiling point:
Covalent compounds generally have low melting and boiling points compared to ionic compounds. This is because the forces holding covalent molecules together are relatively weak compared to the strong electrostatic forces in ionic compounds. The intermolecular forces between covalent molecules are usually van der Waals forces, which are weak compared to the ionic bonds in salts.

Solubility in water:
Covalent compounds can be soluble or insoluble in water, depending on their polarity. Polar covalent compounds have a partial positive and partial negative charge, which allows them to interact with the polar water molecules through intermolecular forces. These compounds are usually soluble in water. On the other hand, nonpolar covalent compounds do not have a charge separation and cannot form strong interactions with water molecules, making them generally insoluble.

Formation between two atoms of metals and nonmetals:
Covalent compounds are typically formed between two nonmetal atoms. Nonmetals have a higher electronegativity, which means they have a greater tendency to attract electrons. When two nonmetals bond, they share electrons to achieve a stable electron configuration. Examples of covalent compounds include water (H2O), carbon dioxide (CO2), and methane (CH4).

Sharing of electrons in the bonding atoms:
In a covalent bond, the atoms share one or more pairs of electrons. This sharing allows each atom to achieve a stable electron configuration by filling their valence shells. The shared electrons are attracted to both nuclei, creating a bond that holds the atoms together. The strength of the covalent bond depends on the number of shared electrons and the distance between the nuclei.

Overall, covalent compounds have distinct properties such as low melting and boiling points, solubility in water depending on polarity, formation between nonmetal atoms, and the sharing of electrons in the bonding atoms. These properties are a result of the nature of covalent bonding and the intermolecular forces between covalent molecules.
