COMEDK · Chemistry · 4. Chemical Bonding and Molecular Structure
For a stable molecule the value of bond order must be
- A negative
- B positive
- C zero
- D there is no relationship between stability and bond order
Answer & Solution
Correct Answer
(B) positive
Step-by-step Solution
Detailed explanation
For a stable molecule the value of bond order must be positive. \(\because\) Stability is directly proportional to bond order.
