Calculate its bond order and predict its magnetic behaviour 2 See answers merielalex merielalex BO = [Nb-Na] = [10-4] = 3 Since all the electrons in nitrogen are paired, it is diamagnetic molecule. Bond energy calculations. is 3.0 × 10 –25 J, calculate its wavelength. Quick overview of what the labels correspond to what MOs: 1a_1 is the sigma_(2s) bonding MO. For example, sulfur dioxide has three bonds: a single bond for sulfur oxide in one Lewis structure and a double bond for sulfur oxide in a different Lewis structure within the molecule. Bond order is 3 in N2 since it has a triple bond. Johnny D this is wrong. 7 years ago. To learn how to determine a bond order at a glance, keep reading! N 2 + ion is formed by the loss of one electron from the N 2 molecule. For Figure-2, Bond order= 2 1 0 − 5 = 2 5 = 2. You can calculate the energy change in a reaction using average bond energies. Bond order formula is given as below \(Bond order = \frac{1}{2}\left [ a – b \right ]\) where Source(s): calculate bond order o2: https://tr.im/tWp5h. 0 1. answer is 2. This gives a bond order of 1.5, which is the average value of the three bonds. asked Jun 7, 2018 in Chemistry by Nisa (59.6k points) chemical bonding and molecular structure; class-11 +1 vote. Therefore, the correct order of stability is N22- < N2– = N2+ < N2. Explanation: The order of stability is directly proportional to the bond order. Determining the bond order starting from a Lewis structure is a task that can range from very easy to rather difficult. CBSE CBSE (Science) Class 11. O2^- has 17 valence electrons.
