Question

In an experiment, 𝑚 grams of a compound X (gas/liquid/solid) taken in a container is loaded in a balance as shown in figure I below. In the presence of a magnetic field, the pan with X is either deflected upwards (figure$$ $$II), or deflected downwards (figure$$ $$III), depending on the compound X. Identify the correct $$statement(s)$$

Infinity Learn · Accepted Answer

Paramagnetic compound (X) are attracted towards magnetic field and the pan is deflected downwards. While the Diamagnetic compound (X) are repelled by magnetic field and pan is deflected upward.(A) X⇒$$H2O$$→Diamagnetic (correct)(B) X⇒$$K4Fe(CN)6(s)$$→ Diamagnetic (correct)  Here $$Fe2++$$ Strong field ligand →$$3d6$$⇒$$t2g6$$,$$eg0$$ (C) X⇒$$O2$$→ Paramagnetic (correct) Here $$O2(g)$$ is paramagnetic due to $$two-unpaired$$ electrons present in π$$*$$ (antibonding$$ $$orbitals). (D) X⇒$$C6H6($$ℓ$$)$$→ Diamagnetic (Incorrect) It is due to presence of $$0$$ unpaired electrons
