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:
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:
A
Both Statement I and Statement II are true
B
Both Statement I and Statement II are false
C
Statement I is true but Statement II is false
D
Statement I is false but Statement II is true
Explanation
Both statements are false: bond order zero implies no chemical bond (molecule does not exist), and bond length is inversely proportional to bond order.
Detailed Solution
In Molecular Orbital Theory, a bond order of zero indicates that bonding electrons equal antibonding electrons, meaning no net attractive bonding exists and the molecule is completely unstable/does not exist (Statement I is false). As bond order increases, atoms are pulled closer by stronger shared electron density, so bond length decreases (Statement II is false). Hence, both statements are false.
