This browser does not support the video element. Diamagnetism is a property that opposes an applied magnetic field, but it's very weak. Bond order, as introduced by Linus Pauling, is defined as the difference between the number of bonds and anti-bonds.. Ans: The stabilities of these can be … Bond Order. I always thought bond order corresponded to the number of bonds. B3+ is the normal oxidation state. To get a negative charge on O2, you would have to have a single bond, so bond order is 1. It has a bond order of 2.5 and is a paramagnetic molecule. Which one is the most stable: H 2, H 2 +, or H 2-? In a covalent bond between two atoms, a single bond has a bond order of one, a double bond has a bond order of two, a triple bond has a bond order of three, and so on. However, when you draw the Lewis structure of B2, you get a triple bond. 10 years ago. Calculate bond order and mention its magnetic property. Best answer. Trending Questions. The bond order shows the number of chemical bonds present between a pair of atoms. Greater value of bond order for H 2 molecule than H 2 + ion shows that two H 2 molecule is more stable than H 2 +.. The Bond order of NeF+ is 1.0. Explain. You can see that "CO" is not (as it has zero unpaired electrons), but "NO" is (it has one unpaired electron). Thus Decreasing order of stability is: O 2 > O 2-> O 2-2. Answer Save.

Write the `MO` electron distribution of `O_(2)`.Specify its bond order and magnetic property. What is the bond order of Li2−? So the bond order of B2 is equal to 1, which you can get by drawing the molecular orbital diagram and performing the equation Bond Order = .5 * (# of bonding electrons - # of antibonding electrons). What is its magnetic property? The bond order of OF+ is 2.0. Bond order value of 1 means that two hydrogen atoms are connected by a single bond.. With the increase in number of electrons in anti-bonding orbital the stability and bond order of the molecule decreases. Bond order is 3 in N2 since it has a triple bond. Source(s): https://shrinkurl.im/a8UOa. Notice this is a good example of making the ionized NO + stabilize the bond and generate a triple bond, also changing the magnetic property to diamagnetic. I disagree with Silvio Levy that the triplet ground state of $\ce{B2}$ is completely unexpected. "O"_2 is well-known to be paramagnetic, and it is one of the successes of molecular orbital theory.
