Which of the following is paramagnetic ? (a) O-2 (b) CN- (c) CO (d) NO+

Question 1

Which of the following is paramagnetic ?

(a) O-2

(b) CN-

(c) CO

(d) NO+

Question 2

**Correct option(a) O-2**

Explanation:

CN- , CO and NO+ are isoelectronic with 14 electrons each and there is no unpaired electrons in the MO configuration of these species. So these are diamagnetic. O-2 is paramagnetic due to the presence of one unpaired electron.
