What is breaking and making of bonds in chemical reaction called

Open in App

Solution

During a chemical reaction:

Bonds in the reactants are broken

New bonds are made in the products

Energy is absorbed to break bonds. Bond-breaking is an endothermic process.

Energy is released when new bonds form. Bond-making is an exothermic process.

Whether a reaction is endothermic or exothermic depends on the difference between the energy needed to break bonds and the energy released when new bonds form. If more heat energy is released when making the bonds than was taken in when they broke, the reaction is exothermic.

breaking of bond is called bond disassociation.

Making of bond is just bond formation,
The differences between types of reactions Type of reaction Explanation

Endothermic Energy absorbed is more than the energy released

Exothermic Energy released is more than the energy absorbed


Endothermic	Energy absorbed is more than the energy released
Exothermic	Energy released is more than the energy absorbed
