Question

What happens to chemical bonds during chemical reactions?

Answer 1

Explanation:

During chemical reactions, the bonds that hold molecules together break apart and form new bonds, rearranging atoms into different substances. Each bond requires a distinct amount of energy to either break or form; without this energy, the reaction cannot take place, and the reactants remain as they were.

Answer 2

Some chemical bonds are broken down and new ones are created in chemical reactions.

• This above statement is the most important aspect of chemical changes.

• Whenever one or more substances undergo chemical changes, some of the chemical bonds are broken down and new ones are created.

• The chemical reaction starts whenever the energy content of the reactants reach the activation energy.

Let's take the following example :

$\bf Na_{2}SO_{4}+BaCl_{2}\rightarrow BaSO_{4}+NaCl$

• Here the bonds between Na+ and $SO_{4}^{2-}$ is broken down and new bonds between Na+ and Cl- are created.

• This is an example of Double-Displacement reaction.
