Given below are two statements.

Statement I:

O X_{2}

Cu X^{2 +}

and

Fe X^{3 +}

are weakly attracted by magnetic field and are magnetized in the same direction as magnetic field.
Statement II : NaCl and

H X_{2} O

are weakly magnetized in opposite direction to magnetic field.
In the light of the above statements, choose the most appropriate answer form the options given below :

(A)Both Statement I and Statement II are correct.✓ Correct
(B)Both Statement I and Statement II are incorrect.
(C)Statement I is correct but Statement II is incorrect.
(D)Statement I is incorrect but Statement II is correct.

Answer: (A)

Solution

O X_{2}

Cu X^{2 +}

, and

Fe X^{3 +}

all have unpaired electrons, making them paramagnetic. Paramagnetic substances are weakly attracted by a magnetic field and are magnetized in the same direction as the applied field.

NaCl and

H X_{2} O

have all electrons paired, making them diamagnetic. Diamagnetic substances are weakly repelled by a magnetic field (magnetized in the opposite direction).

Both statements are correct. The answer is (A).
