WebAs bond length increases, bond strength decreases. The lower is the strength of a bond, the more is its reactivity as it is easier to break. Hence the relative order of reactivity for CH3Cl, CH3Br and CH3I will be. CH3I > CH3Br > CH3Cl but CH3F is exception,CH3F have highest dissociation energy than other halide . WebKeeping the overlap of orbitals in mind, the bond in molecular hydrogen is average as far as covalent bonds go. Molecular oxygen's double bond is stronger at 498 kJ/mol primarily because of the increased orbital overlap from two covalent bonds. And this idea continues with molecular nitrogen which has a triple bond and a bond energy of 945 kJ/mol. WebBonds of the same order between different atoms show a wide range of bond energies, however. Table 9.10.1 lists the average values for some commonly encountered bonds. Although the values shown vary widely, … fairy tail 40 rész
