Question

Identify the type of chemical bond in a molecule reactant

Answer 1

Draw the electron-dot (Lewis) structure of O2. You will see that there is a double bond, thus making the chemical bond a covalent bond since they have to share a pair of electrons in order to complete their octet.

Answer 2

Answer : The type of chemical bond form in $O_2$ molecule is covalent bond.

Explanation:

Ionic bond : It is defined as the bond that is formed by complete transfer of electrons from one atom to another atom.

That means, the atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom.

The ionic bond is usually formed between a metal and a non-metal.

Covalent bond : It is defined as the bond which is formed when sharing of electrons takes place between the atoms.

This is usually formed between two non-metals.

The given reaction is:

$O_2+Energy\rightarrow O(g)+O(g)$

In this reaction, the reactant is $O_2$ molecule.

In $O_2$ molecule, oxygen is non-metal. So, two oxygen atom will form a covalent bond by the sharing of four electrons.

Hence, the type of chemical bond form in $O_2$ molecule is covalent bond.
