Chemical reactions involve breaking and forming bonds from "summary" of NCERT Chemistry Class 11 - [CBSE Board] by Dr. S. C. Rastogi, ,Er. Meera Goyal
Chemical reactions are processes in which substances undergo transformations to form new substances. These transformations involve the breaking of existing bonds between atoms in the reactant molecules and the formation of new bonds to create products. The breaking and forming of bonds are fundamental to understanding how chemical reactions occur. When two or more reactant molecules come into contact with each other, the bonds holding their atoms together are disrupted. This requires an input of energy to overcome the forces holding the atoms in place. As a result, the original bonds are broken, and the atoms are free to rearrange themselves to form new bonds with other atoms. This rearrangement leads to the formation of new molecules, which are the products of the reaction. The breaking of bonds is an endothermic process because it requires energy to break the existing bonds. This energy is often supplied in the form of heat, light, or electricity. Once the bonds are broken, the atoms are in a high-energy state and are ready to form new bonds wit...
