Among the following, the species having the smallest bond is

$NO^-$

$NO^+$

$O_2$

$NO$

(AIEEE-2012)

Solution

$NO^-(16) – B.O. – 2\,\,\,\,\,\,\,\,\,\,O_2(16) – B.O. – 2$
$NO^+(14) – B.O. – 3\,\,\,\,\,\,\,\,\,\,NO(15) – B.O. -2.5$
Higher the bond order lower is the bond length . Hence $NO^+$ will have smallest bond.

When $O _2$ is adsorbed on a metallic surface, electron transfer occurs from the metal to $O _2$. The $TRUE$ statement$(s)$ regarding this adsorption is(are)

$(A)$ $O _2$ is physisorbed

$(B)$ heat is released

$(C)$ occupancy of $\pi_{2 p }^*$ of $O _2$ is increased

$(D)$ bond length of $O _2$ is increased
