Question

Match the following .

Set -I Set -II

A) Ferromagnetism 1)$9.273\times {10}^{-24}J.tesl{a}^{-1}$

B) Paramagnetism 2) $Fe,Co,Ni$

C) Diamagnetism 3) $C{r}^{2+},F{e}^{3+},M{n}^{2+}$

D) Bohr Magneton 4) $Z{n}^{+2},C{u}^{+},S{c}^{+3}$

The correct order of matching is (express in the order A, B, C and D)

• A. 4 2 3 1
• B. 2 3 4 1
• C. 1 2 3 4
• D. 3 1 2 4

Answer 1

The correct option is B 2 3 4 1

Ferromagnetism $Fe,Co,Ni$

Paramagnetism $C{r}^{2+},F{e}^{3+},M{n}^{2+}$ (due to presence of unpair electron)

Diamagnetism $Z{n}^{+2},C{u}^{+},S{c}^{+3}$ (due to absence of unpair electron)

Bohr Magneton $9.273\times {10}^{-24}J.tesl{a}^{-1}$
