Question

Which of the following molecules(s) show/s paramagnetic behavior?

(A) \(O_2\)

(B) \(N_2\)

(C) \(F_2\)

(D) \(S_2\)

(E) \(Cl_2\)

Choose the correct answer from the options given below:

(1) \(\text{B only}\)

(2) \(\text{A }\& \ \text{C only}\)

(3) \(\text{A }\& \ \text{E only}\)

(4) \(\text{A }\& \ \text{D only}\)

Answer 1

Correct option is:  (4) \(\text{A }\& \ \text{D only}\)

		No. of unpaired \(e^-\)
(A)	\(O_2\)	2
(B)	\(N_2\)	0
(C)	\(F_2\)	0
(D)	\(S_2\)	2
(E)	\(Cl_2\)	0

If species contain unpaired electron than it is paramagnetic. 

So \(A \ \& \ D\) are paramagnetic.
