Question

Find out the bond order in He 2, He 2+, O 2 and O 2+, respectively (A) 0,0.5,2 and 3 (B) 0.5,0,3 and 2 (C) 0,0.5,2 and 1 (D) 0,0.5,2 and 2.5

Bond order =( text bonding electrons - text antibonding electrons /2) Molecules Bond order He 2 (2-2/2)=0 He 2 (2-1/2)=0.5 O2 (10-6/2)=2 O 2+ (10-5/2)=2.5

Molecules	Bond order
$H e_{2}$	$\frac{2 - 2}{2} = 0$
$H e_{2}$	$\frac{2 - 1}{2} = 0.5$
$O_{2}$	$\frac{10 - 6}{2} = 2$
$O_{2}^{+}$	$\frac{10 - 5}{2} = 2.5$

Q. Find out the bond order in $H e_{2}, H e_{2}^{+}, O_{2}$ and $O_{2}^{+}$ , respectively

$0, 0.5, 2$ and $3$

$0.5, 0, 3$ and $2$

$0, 0.5, 2$ and $1$

$0, 0.5, 2$ and $2.5$

Bond order $= \frac{bonding electrons - antibonding electrons}{2}$

Molecules Bond order

$H e_{2}$ $\frac{2 - 2}{2} = 0$

$H e_{2}$ $\frac{2 - 1}{2} = 0.5$

$O_{2}$ $\frac{10 - 6}{2} = 2$

$O_{2}^{+}$ $\frac{10 - 5}{2} = 2.5$

Q. Find out the bond order in He2​,He2+​,O2​ and O2+​, respectively
