Question

What will be the nature of the chemical bond between $ C $ , $ O $ and $ Cl $ ?
(A) Only ionic
(B) Only covalent
(C) Coordinate bond
(D) Both ionic and covalent

Answer 1

Hint: To solve this question we will proceed by understanding the definition and each type of bond in a brief. So Ionic bonds are formed where there is complete transfer of electrons from one atom to the other. And as a result, a positively charged ion and a negatively charged ion are formed.

Complete answer:
As ionic bonds involve complete transfer of electrons, it is generally formed with high electronegative elements like fluorine, chlorine and nitrogen.
Whereas, in covalent bonding, there is a sharing of electrons. An Atom shares its electron with another atom to complete its octet. In this bond electrons are not completely transferred and the positive and the negative ions are not formed.
Here, also more electronegative atoms are not needed for the covalent bond formation since it is a sharing bond.
So, by looking at the given atoms i.e. $ C $ , $ O $ and $ Cl $ , we can say it will prefer covalent bonding.
Explanation: As a carbon atom, $ C $ has four electrons in its valence shell, so to complete its octet it will share the electrons with the Oxygen atom and the chlorine atom through covalent bonds.
There is no ionic bonding in this molecule as there is no complete transfer of electrons from one atom to the other.
So, the correct answer is option B. i.e. Only Covalent bond.

Note:
Coordinate bonds are also known as dative bonds. They are actually an altered form of the covalent bond. Coordinate bonds also involve the sharing of electrons between the two atoms but in this bonding both the electrons are shared from the one atom only.
