The difference between exothermic

and endothermic reactions

Endothermic Reactions

Endothermic reactions, not like Exothermic reactions, take more energy in order to build a new bond. As for an Exothermic reaction, it takes less energy to break bonds in reactants to create new bonds. So, therefore, Endothermic reactions and Exothermic reactions differ in a way that one needs and uses more energy than the other.
