Since c2 is known to have zero unpaired electrons, it is diamagnetic in nature. Explanation: The Lewis structure of O2 gives a misleading impression. Follow edited Mar 11, 2015 at 19:29. jerepierre. A. This is due to the parallel spin of electrons in orbitals. Which theory shows that oxygen is paramagnetic? The element hydrogen is virtually never called 'paramagnetic' because the monatomic gas is stable only at extremely high temperature; H atoms combine to form molecular H 2 and in so doing, the magnetic moments are lost ( quenched ), because of the spins pair. Answer:Paramagnetic species contains unpaired electrons in their molecular orbital electronic configuration. Match the picture below with the substance and indicate the correct summary of this behavior. Radiation sensitization using texaphyrinsRadiation sensitization using texaphyrins .. .. So oxygen should be diamagnetic.Yet oxygen is paramagnetic. ozone; Share. The paramagnetic elements are those that have unpaired electrons. Hence, option C is correct. 615. It is paramagnetic because of an unpaired electron. Molecular orbital theory predicts a configuration with a bond order of 2 and two unpaired electrons, in agreement with experimental results. Thus, among the given species only O-2 is paramagnetic. Liquid Nitrogen N21) This substance is C. Diamagnetic D. Paramagnetic E. Ferromagnetic It is F. Strongly attracted G. Attracted In a magnetic field it is H. Slightly; Question: Liquid oxygen and liquid nitrogen behave differently in a magnetic field. Asked By . Is liquid oxygen diamagnetic?
