Question

the bond order of HeH- is

Answer 1

The bond order of HeH is One.

Answer 2

The bond order of$HeH-$ bond is 1

Bond order

The bond order shows the number of chemical bonds present between a pair of atoms. For instance, the bond order of diatomic nitrogen N≡N is 3 and bond order between the carbon atoms in H-H≡C-H is also three. The bond order describes the stability of the bond.

Solution

The bond energy order of $\mathrm{He}^{2+}$

is $\frac{(2-2)}{2}=0$

and $\mathrm{HeH}^{+}$is $\frac{3-1}{2}=1$.

Hence bond order of HeH- is 1
