Per NCERT §4.7.5 (general rule), how does BOND LENGTH relate to BOND ORDER in MOT?
ABond length DECREASES as bond order INCREASES (higher b.o. → stronger + shorter bond)
BBoth unrelated
CBond length increases as bond order increases
DBond length = b.o.²
Answer & Solution
Correct answer: A. Bond length DECREASES as bond order INCREASES (higher b.o. → stronger + shorter bond)
Per NCERT §4.3.4 + 4.7.5, higher bond order → shorter + stronger bond. b.o. is an inverse measure of bond length.
