Explain the following observations: (1) H_(2)^(+) ion is more stable than H_(2)^(-) ion even though the bond orders of both the ions are the same. (2) When a magnet is dipped in a jar containing liquid oxygen, some oxygen molecules cling to it.

Explain the following observations: (1) H_(2)^(+) ion is more stable

1.	Explain the following observations: (1) H_(2)^(+) ion is more stable than H_(2)^(-) ion even though the bond orders of both the ions are the same. (2) When a magnet is dipped in a jar containing liquid oxygen, some oxygen molecules cling to it.
Answer» SOLUTION :(1) The antibonding `sigma_(1s)^()` molecular orbital of `H_(2)^(-)` ion contains ONE electron but the antibonding `sigma_(1s)^()` molecular orbital of `H_(2)^(+)` ion contains no electron. Therefore `H_(2)^(+)` ion is more stable than `H_(2)^(-)` ion, even though their bond order are the same. (2) The electronic configuration of oxygen of oxygen molecule `(O_(2))` shows the presence of two unpaired ELECTORNS this suggests that the molecule is paramagneticin nature. thus, when a BAR magnet is dipped in a jar off liquid oxygen, some molecule cling to it.
