Which bond is longer, why? 1. H-H, cl-cl
2. O?, N?
1. The bond length of O2 and N2 molecules is less as compared to H2 and Cl2,as they are doubly and triply bonded molecules.
2. In H2 and Cl2, the bond length of Cl2 is more as both Cl have 7 electrons in their valence shell, so they repel eachother and bond length increases.
