Given below are two statements : Statement I : A hypothetical diatomic molecule with bond order zero is quite stable. Statement II : As bond order increases, the bond length increase. In the light of the above statements, choose the most appropriate answer from the options given below :

Options

  1. ABoth Statement I and Statement II are true
  2. BBoth Statement I and Statement II are false
  3. CStatement I is true but Statement II are false
  4. DStatement I is false but Statement II are true

Correct answer

B. Both Statement I and Statement II are false

Step-by-step solution

He2Be2Ne2\begin{array}{l}\mathrm{He}_2 \\ \mathrm{Be}_2 \\ \mathrm{Ne}_2\end{array}\right\} Bond order =0 (does not exist)  Statement I is false \begin{aligned} & \text{ Bond order }=0 \text{ (does not exist) } \\ & \text{ Statement } \mathrm{I} \text{ is false }\end{aligned} Bond order ∝1 Bond length \text{ Bond order } \propto \frac{1}{\text{ Bond length }} Statement II is false
