Given below are two statements : In the light of the above statements, choose the most appropriate answer from the options given below:
- Statement I is true but Statement II is false
- Statement I is false but Statement II is true
- Both Statement I and Statement II are true
- Both Statement I and Statement II are false
Answer
(4) Both Statement I and Statement II are false
Solution
Statement I: Bond order = 12(Nb - Na). A bond order of zero means no net bonding, so such a molecule does not exist (e.g. He2, Be2). False.
Statement II: Bond length is inversely related to bond order; as bond order increases, bond length decreases. False.
Answer: (4)
