★When does the breaking of chemical bonds release energy?

Answers
Halogens act as strong oxidising agents because they have high tendency to accept electron, i.e., they have high electron affinity values. The reduction potentials are high ( positive ) and decreased from FF to I .

Explanation:
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, but they are really two separate events. For instance, when you burn methane (natural gas) in your stove, the methane is reacting with oxygen to form carbon dioxide and water. Chemists often write this as:
CH4 + 2 O2 → CO2 + 2 H2O + energy
This balanced chemical equation summarizes the chemical reaction involved in burning methane. The reactants are on the left, the products are on the right, and the arrow represents the moment the reaction happens. But there are a lot of interesting things happening that are hidden behind that arrow. A more detailed equation would look something like this:
CH4 + 2 O2 + a little energy →
C + 4 H + 4 O →
CO2 + 2 H2O + lots of energy
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. On the last line are the final products. It takes a little energy, such as the spark from the igniter in your stove, to get the reaction started. That is because bonds must be broken before the atoms can be formed into new bonds, and it always takes energy to break bonds. Once the reaction has started, the output energy from one burned methane molecule becomes the input energy for the next molecule. Some of the energy released by each bond that is formed in making carbon dioxide and water is used to break more bonds in the methane and oxygen molecules. In this way, the reaction becomes self-sustaining (as long as methane and oxygen continue to be supplied). The igniter can be turned off. If breaking bonds did not require energy, then fuels would not need an ignition device to start burning. They would just start burning on their own. The presence of spark plugs in your car attests to the fact that breaking chemical bonds requires energy. (Note that the combustion of methane actually involves many smaller steps, so the equation above could be expanded out into even more detail.)
