Question

Most ionic compound among the following is:
A.Sodium fluoride
B.Sodium chloride
C.Sodium bromide
D.Sodium iodide

Answer 1

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.We will understand the type of bonding formed we can get and observe the reasons observing the bonding. Then we can pick the correct approach to observe the difference between the options.

Complete step by step answer:
An ionic compound is a compound that is formed when atoms combine by the help of ionic atomic bonding. Ionic bonding is the bond formation in which the complete transference of the electrons take place. This leads to one atom being anion and one cation.
Now the power and the magnitude of the ionic bonding depends on various reasons. Some of them are :
-The difference of the electronegativity of the participating atoms.
-The size of both the atoms after and before the bonding.
-The magnitude at which the reaction takes place for the bonding.
-The electron losing and acceptance capacities of the atoms participating in the ionic bonding.
By observing the given compounds we get that sodium is common among all of them. Therefore it makes our work easier and specific. We have the common metal so we have to observe the non-metal to have the correct approach.
We have to implement the rule of the difference of the electronegativity of the participating atoms. According to which more the difference better the bond. So by that we can get that Fluorine will make the finest ionic bond with the Sodium.
Therefore the answer is the option A, Sodium fluoride.

Note:
The term ionisation refers to the process of forming ions. They can be either of the anion or the cation. In the process of the ionic bonding, before the process of the bonding the process of ionisation takes place. That’s why they are the strongest type of bonds due to electrostatic attraction.
