When we draw MO diagram for dihydrogen anion ( H2-) we find one unpaired electron in antibonding sigma orbital. If the the bond order is fractional, species are paramagnetic. The other two are diamagnetic. Be2^2- 2. 1 1. As already pointed out the N species have to be paramagnetic because they are odd e⁻ systems. In paramagnetic materials, the magnetic moments of the electrons don't completely cancel each other out. Paramagnetic molecules get attracted towards external magnetic field and diamagnetic repel the external magnetic field. Which is the light metal available with better Hardness ? ? 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. N2 So, in KO2 the oxygen atoms bear -1/2 oxidation state and they also behave as a free radical species, having an unpaired electron. Here,Li2- is more stable due to the presence of anti bonding electrons. 1 B. N2 molecules are diamagnetic. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. odd number of electrons, that specieces is paramagnetic.

Paramagnetic Substances: Paramagnetic substances are … Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. O_2^- in KO2 has 17 electrons, species with odd electrons are always paramagn 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. Other species do not have unpaired electron so they are diamagnetic in nature. Relevance. Hence, it is paramagnetic in nature. Paramagnetic molecules are attracted toward a magnetic field. If it has any unpaired electrons it will be paramagnetic and otherwise it (a) NO (b) CO (c) O2 (d) B2. Lv 4. Due to their spin, unpaired electrons have a magnetic dipole moment and act like tiny magnets. 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. In the following which of the two are paramagnetic;N2,CO,B2,NO2 2 See answers aqibkincsem aqibkincsem "CO and B2 are paramagnetic in nature. It is paired with a species that has an opposite magnetic pole. The neutral oxygen is paramagnetic according to MO theory because it ends up with two unpaired electrons in two degenerate pi antibonding molecular orbitals. N O, N O 2 both have one unpaired electron so they both are paramagnetic in nature i.e. It is a permanent magnet. 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. Diamagnetism occurs when orbital electron motion forms tiny current loops, which produce magnetic fields. O 2 and O 2 − are paramagnetic while O 2 2 − is diamagnetic. To identify the magnetic nature we need to check the molecular orbital configuration, all orbitals are fully occupied, species is diamagnetic while when one or, Which of the following species is paramagnetic ? Paramagnetic species have unpaired electrons. An atom could have ten diamagnetic electrons, but as long as it also has one paramagnetic electron, it is still considered a paramagnetic atom. To know the magnetic character of molecules we can use MO diagram. Given the species : N2, CO, CN^- and NO^+ . We have step-by-step solutions for your textbooks written by Bartleby experts!
