Hence, I am unable to grasp the formula correctly. Diamagnetism occurs when orbital electron motion forms tiny current loops, which produce magnetic fields. 30) Consider the species N2', N2, and N2. A) only Cl2 ... Q. If all electrons are paired, then the ion/molecule is diamagnetic The MO electronic configurations are given. Add your answer and earn points. paramagnetic. Paramagnetic species have unpaired electrons. 1 1. This further continues by the stability of atomic orbitals. A species is said to be diamagnetic when it has all the paired electrons. (But you're in luck, because I've already drawn it out before if you want to see.). The instantaneous reaction rate is always equal and constant. Similarly if the species contain unpaired electron it is said to be paramagnetic. 1. Use the MO energy diagram as provided on the right. Here is a trick to do this question without having to invoke too many MO diagrams, as there is almost no way you could have seen the MO diagram of #"NO"^(-)# without the impressive ability to draw one from scratch. Given the species : N2, CO, CN^- and NO^+ . Here,Li2- is more stable due to the presence of anti bonding electrons. Electronic configuration of Scandium; Sc = 21 = 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹ Sc³⁺ = 1s², 2s², 2p⁶, 3s², 3p⁶ Hence in Sc³⁺ there is no unpaired electron. is odd electron system.

If the bond order is integer, species is diamagnetic ( except 10 electron, 16 electron species). Be2^2- 2. An atom could have ten diamagnetic electrons, but as long as it also has one paramagnetic electron, it is still considered a paramagnetic atom. Which of the following species is not paramagnetic ? Answer Save. N O, N O 2 both have one unpaired electron so they both are paramagnetic in nature i.e. Hence, it is paramagnetic in nature. Atoms or molecules with an odd number of electrons are paramagnetic. Due to their spin, unpaired electrons have a magnetic dipole moment and act like tiny magnets. | EduRev Class 11 Question is disucussed on EduRev Study Group by … All materials are diamagnetic. Which of the following species is not paramagnetic ? To identify the magnetic nature we need to check the molecular orbital configuration, lf all orbitals are fully occupied, species is diamagnetic while when one or.

Hence calculate the bond order for F 2 and B 2 and indicate whether these molecules are paramagnetic or diamagnetic. It has one or more unpaired electrons. Which of these species will be paramagnetic? 1 B. The other two are paramagnetic because they have an odd number of electrons so it doesn’t matter what kind of bonding they are involved in, the electrons cannot be all paired up. Zirp. The neutral oxygen is paramagnetic according to MO theory because it ends up with two unpaired electrons in two degenerate pi antibonding molecular orbitals. If unpaired electrons are present in an ion/molecule, then it is paramagnetic. We know that a molecule becomes paramagnetic due to the presence of unpaired electrons. species like B2 are paramagnetic due to presence of two unpaired electrons in pi 2p bonding molecular orbitals according to molecular orbital theory. A paramagnetic electron is an unpaired electron. When we draw MO diagram for dihydrogen anion ( H2-) we find one unpaired electron in antibonding sigma orbital. Join Yahoo Answers and get 100 points today. It so happens that the molecular orbital description of this molecule provided an explanation for a long-standing puzzle that could not be explained using other bonding models.
