Bond order of He2+ arrow 0.5 O2- arrow 1.5 C2 arrow 2 NO arrow 2.5

Q. Which of the following is a correct order of bond order ?

$C_{2} < NO < H e_{2}^{+} < O_{2}^{-}$

$NO < C_{2} < O_{2}^{-} < H e_{2}^{+}$

$H e_{2}^{+} < O_{2}^{-} < NO < C_{2}$

$H e_{2}^{+} < O_{2}^{-} < C_{2} < NO$

Bond order of $H e_{2}^{+} \to 0.5$
$O_{2}^{-} \to 1.5$
$C_{2} \to 2$
$NO \to 2.5$

Q. Which of the following is a correct order of bond order ?

C2​<NO<He2+​<O2−​

NO<C2​<O2−​<He2+​

He2+​<O2−​<NO<C2​

He2+​<O2−​<C2​<NO

Bond order of He2+​→0.5 O2−​→1.5 C2​→2 NO→2.5

$C_{2} < NO < H e_{2}^{+} < O_{2}^{-}$

$NO < C_{2} < O_{2}^{-} < H e_{2}^{+}$

$H e_{2}^{+} < O_{2}^{-} < NO < C_{2}$

$H e_{2}^{+} < O_{2}^{-} < C_{2} < NO$

Bond order of $H e_{2}^{+} \to 0.5$
$O_{2}^{-} \to 1.5$
$C_{2} \to 2$
$NO \to 2.5$
