The dissociation energies are different because bonds don't all break at once Most chemical processes happen step by step. Even in simple molecules like methane where there are only 4 bonds, bond dissociation almost always occurs stepwise. The implication of this is that you would not expect each step to involve the same energy (and this applies whatever ...

According to VSEPR theory, the bond angles in case of CH3Cl and CH3Br is based on bond pair - bond pair repulsion only as there are no lone pairs in them. The bond pair electrons are spread within the bond distance between the bonded atoms. The bond distance for C-Br bond (1.934 A°) is larger than the C-Cl bond (1.781 A°) and also there is not effective ...
