Given below are two statements Statement I: A hypothetical diatomic molecule with bond order zero is quite stable.

Question

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. A. Both Statement I and Statement II are true
2. B. Both Statement I and Statement II are false (Correct answer)
3. C. Statement I is true but Statement II is false
4. D. Statement I is false but Statement II is true

Correct Answer

Option B — Both Statement I and Statement II are false

Detailed Solution & Explanation

The correct answer is Both Statement I and Statement II are false.

Key Points

• A molecule with zero (or negative) bond order is unstable and does not exist — so Statement I is false.
• Bond length is inversely related to bond order: as bond order increases, bond length decreases — so Statement II is false.
