Why does breaking a chemical bond always take energy?

[E,Z]-2-4-diallyl trans-3,4-dimethyl-cyclobutene Fig 25 {E,Z]-2,4-diallyl turns into cis-3,4-dimethyl-cyclobutene when it is heated; turns into trans-3,4 -dimethyl-cyclobutene when illuminated. Seen from the above formula , when heated, each bond breaks at the same side of the two double bonds of [E,Z]-2,4-diallyl 。

How does breaking chemical bonds work?

The breaking of chemical bonds never releases energy to the external environment. Energy is only released when chemical bonds are formed. In general, a chemical reaction involves two steps: 1) the original chemical bonds between the atoms are broken, and 2) new bonds are formed. These two steps are sometimes lumped into one event for simplicity, ...

What is the first line of the equation?

The first line of the equation contains the original reactants : methane molecules and oxygen molecules. The first arrow represents the breaking of the bonds, which requires energy. On the middle line are the atoms, now broken out of molecules and free to react. The second arrow represents the forming of new bonds.

What is the difference between endothermic and exothermic reactions?

(Endothermic reactions can also proceed on their own if there is enough external energy in the form of ambient heat to be absorbed.) Exothermic reactions tend to heat up the surrounding environment while endothermic reactions tend to cool it down.

What is the total energy of a reaction?

The total energy input or output of a reaction equals the energy released in forming new bonds minus the energy used in breaking the original bonds. If it takes more energy to break the original bonds than is released when the new bonds are formed, then the net energy of the reaction is negative. This means that energy must be pumped into ...
