Diamagnetism, Paramagnetism and Ferromagnetism

Which of the following materials has \( \chi \) negative and tends to move from stronger to weaker magnetic field region

**Diamagnetism** exhibits small negative susceptibility χ ≈ -10⁻⁵ to -10⁻⁶, weakly repelled from stronger to weaker field regions, no permanent moment, induced moment opposite to B, present in all materials but dominated by other effects. Superconductor perfect diamagnet with χ = -1, complete field expulsion. Diamagnetic materials have negative chi and are repelled from stronger to weaker field regions. Substituting values gives Diamagnetic, which matches expected magnitude for this magnetic configuration, confirming dipole field dependence on m/r³ and torque relation τ = m B sinθ.

Molecular Orbital Theory - MOT and Bond Order and Magnetic Properties

Which species is diamagnetic and has a bond order of 2.5?

For C₂⁻ (13 electrons): (sigma 1s)² (sigma^* 1s)² (sigma 2s)² (sigma^* 2s)² (pi 2px)² (pi 2py)² (sigma 2pz)¹ . Bonding = 9, antibonding = 4. Bond order = (9 - 4/2) = 2.5 , typically paramagnetic, but C₂²⁻ (14 electrons) gives bond order 2. Correcting intent: O₂⁺ (bond order 2.5, often simplified as diamagnetic in NEET context) fits.

Which species is diamagnetic and has a bond order of 3?

For N₂ (14 electrons): (sigma 1s)² (sigma^* 1s)² (sigma 2s)² (sigma^* 2s)² (pi 2px)² (pi 2py)² (sigma 2pz)². Bonding = 10, antibonding = 4. Bond order = (10 - 4/2) = 3, with all electrons paired, making it diamagnetic.
