Share with your friends. N 2 2-molecule is more paramagnetic. Fill in the molecular orbital energy diagram for N22- and then answer the following questions. Therefore, the correct order of stability is N22- < N2– = N2+ < N2. Whether a molecule is paramagnetic or not is only explained using molecular orbital theory. Ask Question + 100. The given molecule is paramagnetic due to two unpaired electrons in an antibonding orbital. O2 does not have s-p mixing, so the σp orbital fills before the π orbitals. ANSWERS TO MOLECULAR ORBITALS PROBLEM SET 1. 2. The paramagnetic substances are attracted by the magnetic field. Relevance. c) Identify the MAGNETIC properties (paramagnetic or diamagnetic) 24. Still have questions? Using the MO diagrams, predict the bond order for the stronger bond in each pair: (a) B 2 or B 2 + (b) F 2 or F 2 + (c) O 2 or O 2 2+ (d) C 2 + or C 2 − In the case of O$_2$ it is found that the lowest energy state is one that has one electron in each of two orbitals. Explain why N 2 2+ is diamagnetic, while O 2 4+, which has the same number of valence electrons, is paramagnetic. a) The bond order of O2 is 2.5 and it is paramagnetic b) The bond order of O2 is 1.5 and it is paramagnetic c) The bond order of O2 is 2 and it is diamagnetic In contrast, paramagnetic and ferromagnetic materials are attracted by a magnetic field. Get your answers by asking now. Given N22- , using molecular orbital and valence bond theory ; a) Write molecular orbital configurations. Nitrogen (N$_2$) is not paramagnetic but diamagnetic.
