Title: Species which show an increase in bond order when you take away one electron from the molecule/mole Post by: louist on Nov 14, 2021 Identify all of the following species which show an increase in bond order when you
take away one electron from the molecule/molecular ion? He2+ , B2, C2-, N2, O2+, F2-, Ne2+, H2 Title: Re: Species which show an increase in bond order when you take away one electron from the ... Post by: bio_man on Nov 14, 2021 Hi @louist, I'm not entirely sure on this one, but here are my findings:
bond order = (bonding electrons - anti-bonding electrons) / 2 He2+ has 3 electrons, because He normally has 4. Therefore, the bond order is 2-1 / 2 = 0.5. Removing an electron would increase its bond order to 1. B2 has 4 bonding and 2 antibonding, so (4-2) / 2 = 1. Removing one would make the bond order decrease. C2- will have a greater bond order after an electron is removed. N2 has a bond order of 3. Taking away one would make it 2.5 O2+ bond order decreases when it becomes O22+. F2- bond order decreases when an electron is removed. Ne2+ has a bond order of 0.5. Bond order would decrease after removing another electron. H2 has a bond order of 1. H2+ is 0.5. |
