Diamagnetic substances are characterized by paired electrons, e.g., no unpaired electrons. Paramagnetic molecules get attracted towards external magnetic field and diamagnetic repel the external magnetic field. Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. … ? N2O4, the dimer of NO2, is also diamagnetic. Thus, a nitrogen atom is always paramagnetic. However experiments show that it is diamagnetic. Answer = C2Cl4 ( Tetrachloroethylene ) is nonPolar What is polar and non-polar? And, just like nitrogen, each molecule of oxygen behaves like a tiny magnet when it's exposed to a magnet's magnetic field. So paramagnetic materials are also diamagnetic, but because paramagnetism is stronger, that is how they are classified. Chemistry Questions & Answers for CAT,Bank Exams,AIEEE, Bank PO,Bank Clerk,Analyst : Is C2 Paramagnetic or Diamagnetic? Take a look at the molecular orbital diagram for N2. (paramagnetic transition and inner transtion metal ions), orbital filling footnotes (elemental dioxygen), or nitrogen (for its odd number of electrons) and some pluck (NO, NO2 monomer, DPPH, TEMPO; nitronyl nitroxides, verdazyls, etc.). NO has odd number of electrons (7 + 8 = 15) and due to the presence of unpaired electron, it is paramagnetic in the gaseous state.However, in the liquid and solid states, the unpaired electrons are involved in the formation of loose dimer. It's worth noting, any conductor exhibits strong diamagnetism in the presence of a changing magnetic field because circulating currents will oppose magnetic field lines.
