Question

Molecules / ions and their magnetic properties are given below. Molecule/Ion Magnetic property i C 6 H 6 1 Antiferromagnetic ii CrO 2 2 Ferrimagnetic iii MnO 3 Ferromagnetic iv Fe 3 O 4 4 Paramagnetic v Fe 3+ 5 Diamagnetic The correctly matched pairs in the above is (A) i-5 ii-3 iii-2 iv-1 v-4 (B) i-3 ii-5 iii-1 iv-4 v-2 (C) i-5 ii-3 iii-1 iv-2 v-4 (D) i-5 ii-3 iii-1 iv-4 v-2

C 6 H 6 is a diamagnetic substance, as it is weakly repelled by a magnetic field. CrO 2 is a ferromagnetic substance, which is attracted very strongly by a magnetic field. MnO is an antiferromagnetic substance as its domains cancel out each other's magnetic moment. Fe 3 O 4 (magnetite) is a ferrimagnetic substance because in it the magnetic moments of the domains are aligned in parallel and anti-parallel direction in unequal number. Fe 3+(3 d5) is paramagnetic because of the presence of unpaired electrons. Thus, the correct match is i -5, ii -3, iii -1, iv -2, v -4

$i - 5 ii - 3 iii - 2 i v - 1 v - 4$

$i - 3 ii - 5 iii - 1 i v - 4 v - 2$

$i - 5 ii - 3 iii - 1 i v - 2 v - 4$

$i - 5 ii - 3 iii - 1 i v - 4 v - 2$

$i - 4 ii - 5 iii - 1 i v - 2 v - 3$
