i need a detailed explanation.
thank you very much

The amount of energy required for dissociation or breaking of aparticular bond is its bond dissociation energy.
It depends upon a lot of factors:
a) Higher the polarity, greater the B.D energy
b) Larger the saturation in the bond, higher is its B.D energy
c) Higher the bond length, lower the B.D energy.
d) Higher the S - charachter in the bond, greater is its B.D energy.

This is defined as the energy reqd by one mol of a substance to break all the covalent bonds that exists in it & get separated as the constituent atoms in the gaseous state.
In order to break a bond some energy is to be supplied to the substance as cleavage of a bond means that the potential energy of the species increases, this energy is defined as bond dissociation energy.

F(a):F(b)?z (via MO convention) the singly occupied 2pz AO of F(a)(?) overlaps with the corresponding singly occupied 2pz AO of F(b)(?) to provide the F:F(??) ? bond. The bond is gotten smaller by unique intense electronegativity of F. as a fashion to take action overlap the F(a) 2px e? pair interacts with the the F(b) 2px e? pair causing repulsion that weakens the ? bond; a similar is authentic for the 2py e? pair AOs. the region is a commerce-off. For the different halogens, X:X, a similar ? bonding takes position yet now because the bond isn't contrated and little lp-lp repulsion takes position. (The d AOs are center e?s and make no substantial contribution to X-X bonding). The anomalously weak F-F bond is the universal (yet no longer the in straightforward words) clarification for the reactivity of F2. As has been element out the e? affinity for Cl is > than that for F. Now I actually have fooled you with the technology. enable me in basic terms say that i do not trust it truly is the most excellent reason yet i'm saving my reason in the back of yet another day.

Bonds are of different strengths.
Different amounts of energy are required to be applied to a bond in order for it to break (dissociate).
The amount of energy you need to apply to the bond in order for it to dissociate is the bond dissociation energy.
