Question 17

Covalent bonds involve sharing pairs of electrons.

Covalent bonds occur when two atoms share pairs of electrons, allowing them to achieve a more stable electron configuration. This sharing of electrons is fundamental to the formation of molecules.

A) Ionic

Ionic bonds are characterized by the transfer of electrons from one atom to another, resulting in the formation of charged ions. In contrast to covalent bonds, ionic bonding does not involve the sharing of electron pairs, making this option incorrect.

B) Covalent

Covalent bonds specifically involve the sharing of pairs of electrons between atoms. This type of bond is essential in forming molecular compounds and is the correct answer to the question posed.

C) Both

While both ionic and covalent bonds are essential types of chemical bonds, only covalent bonds involve the sharing of electron pairs. Therefore, stating that both types involve sharing is misleading, making this option incorrect.

D) None of the above

This option suggests that neither type of bond involves sharing pairs of electrons, which is inaccurate. Covalent bonds do involve sharing, so this option is also incorrect.

Conclusion

Covalent bonds are defined by the sharing of electron pairs, making option B the definitive correct answer. All other options fail to accurately describe the nature of bonds in relation to electron sharing, reinforcing the distinct characteristics of covalent bonding.
