Question

Consider the following element combinations. Classify the bonds formed between each pair as ionic, polar covalent, or nonpolar covalent qualitatively based solely on each element's position on the periodic table. Do not conduct calculations.

Answer 1

Concepts and reason

The concept used to solve this problem is based on the chemical bonding.

A chemical bond is a permanent attraction between molecules, ions or atoms which allows the formation of chemical compounds.

Fundamentals

A type of chemical bond which includes the electrostatic attraction between oppositely charged ions is called ionic bond.

A type of chemical bond which includes the sharing of electron pairs between atoms is called covalent bond.

In periodic table, the atoms iron, sodium and manganese are metals. The atoms oxygen, nitrogen and chlorine are non-metals.

Thus, based on the position of these atoms in periodic table, the bond formed between the pairs ${\rm{Fe}} - {\rm{O}}$ , ${\rm{Na}} - {\rm{N}}$ and ${\rm{Mn}} - {\rm{Cl}}$ is ionic bond.

The covalent bond formed between ${\rm{S}} - {\rm{S}}$ and ${\rm{Cl}} - {\rm{Cl}}$ are non-polar covalent bond.

The covalent bond formed between ${\rm{O}} - {\rm{F}}$ , ${\rm{P}} - {\rm{Br}}$ and ${\rm{S}} - {\rm{I}}$ are polar covalent bond.

Ans:

Arrange the given compounds as follows:
