Bond order is directly proportional to bond dissociation energy and inversely proportional to bond length i.e. higher the bond order, larger is the bond dissociation energy and smaller is the bond length. Bond order gives an indication to the stability of a bond. If the bond order is 1, 2, 3 the respective bonds will be single, double or triple ...

Bond Order The bond order for a molecule can be determined as follows: bond order = ½ (bonding electrons − antibonding electrons). Therefore, the H 2 molecule has a bond order of ½ (2 − 0) = 1. In other words, there is a single bond connecting the two H atoms in the H 2 molecule.

Nov 07, 2011 · The bonds orders are: Be2 - 0, Li2 - 1, C2 - 2, N2 - 3. The answer therefore, is b. To calculate the bond order between two atoms, you subtract the number of non-bonding electrons from the number of bonding electrons and divide by two. The bond order in H2 = 1/2[2-0] = 1 Bond dissociation energy in H2 molecule is 431.4 kJ mol-1 and bond length is 74 pm. Hydrogen molecule ion, H2+ The molecular ion has only one electron and its electronic configuration is [(1s)1] and the bond order is (Fig 2.58).

Aug 13, 2014 · [H2]^2- the MO scheme is σ(↑↓) σ*(↑↓) with a bond order of 0 (unbound). More advanced MO theory shows that σ* is more destabilized with respect to the constituent 1s AOs than the σ is stabilized so the σ(2e⁻) σ*(2e⁻) configuration is at a higher energy (a repulsive interaction) than two separated He atoms.

Looking on the periodic table, Bromine is in Group 7 or 17. It has 7 valence electrons. We have two of them though. Multiply that by 2, for a total of 14 valence electrons for the Br2 Lewis structure. First, we'll draw two Bromine atoms next to each other. We have 14 valence electrons for Br2. We'll put two between atoms to form a chemical bond.
