Question

calculate the bond order of He2 +

Answer 1

bond order of he 2 +  =

2-2/2 = 0

no bonding occurs

Answer 2

Given:

The given compound is $He_2^+$.

To find:

We have to find the bond order.

Solution:

The given compound is $He_2^+$.

The total number of electrons in $He_2^+$ is 4-1=3.

The electronic distribution of $He_2^+$ is as follows-

$\sigma^2 \sigma *^1$.

The bond order is given as-

B.O=(number of bonding electrons-number of antibonding electrons)/2.

The number of bonding electrons in $He_2^+$ is 2.

The number of antibonding electrons in $He_2^+$ is 1.

Hence bond order is as follows-

B.O=(2-1)/2

B.O=0.5

Hence the bond order of $He_2^+$ is 0.5.
