Question

What are the two main types of chemical bonds that are found in compounds?

Answer 1

Hint: The type of bonding in methane is different from the type of bonding in sodium chloride as in methane both the elements are nonmetals and in sodium chloride, sodium is a metal and chlorine is a non-metal. Sodium chloride can form ions but methane cannot form ions and this is based on the bonding present in them.

Complete answer:
Bonds are the property by which two atoms or elements are joined together to form a compound. Based on the property of the elements the types of bonding are different. The type of bonding in methane is different from the type of bonding in sodium chloride as in methane both the elements are nonmetals and in sodium chloride, sodium is a metal and chlorine is a non-metal.
So, the two main types of bonding are ionic bond and covalent bond. Therefore, the bonding in methane will be covalent because it is formed between nonmetals and the bonding in the sodium chloride is an ionic bond because it is formed between a metal and a nonmetal.
When an ionic bond breaks then there is the formation of ions (cation and anion) and the ionic bond is formed by the transfer of electrons, but when the covalent bond breaks the there is no formation of ions, and the covalent bond is formed by the sharing of electrons between the atoms.
Some other examples of compounds having ionic bonds are $MgC{{l}_{3}}$, $AlC{{l}_{3}}$, etc and the compounds having covalent bond are ${{C}_{6}}{{H}_{6}}$, ${{C}_{2}}{{H}_{6}}$, etc.

Note:
In some compounds, there is another type of bonding present in the compounds, i.e., coordinate bonds in which central metal atoms and ligands are involved. In this ligands donate a pair of electrons to the vacant orbital of the central metal atom.
