Question

The number of species from the following which are paramagnetic and with bond order equal to one is____.

\(H_2,He^{+}_2, O^{+}_2 , N^{2-}_2,O^{2-}_2 ,F_2, Ne ^+_2 ,B_2\)

Answer 1

Correct answer is : 1

	Magnetic behaviour	Bond order
\(H_2\)	Diamagnetic	1
\(He ^+ _2\)	Paramagnetic	0.5
\(O^+_2\)	Paramagnetic	2.5
\(N^{2-}_2\)	Paramagnetic	2
\(O^{2-}_2\)	Diamagnetic	1
\(F_2\)	Diamagnetic	1
\(Ne ^+_2\)	Paramagnetic	0.5
\(B_2\)	Paramagnetic	1
