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 increases.

In the light of the above statements, choose the most appropriate answer from the options given below :

1. Both Statement I and Statement II are true

2. Both Statement I and Statement II are false

3. Statement I is true but Statement II is false

4. Statement I is false but Statement II is true

1 answer

Best answer

Answer: 2. Both Statement I and Statement II are false

Key idea: bond order measures net bonding; it links to stability and bond length.

  • Statement I is false: bond order zero means no net bonding, so such a molecule does not exist (is unstable).
  • Statement II is false: higher bond order means a shorter, stronger bond; bond length decreases.

Both false: option (2).
