The lowest O — O bond length in the following molecule is : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Determine the O-O bond order for each species. O2 contains a double bond (bond order = 2.0). Step 2: H2O2 has a single bond (bond order = 1.0). O3 is a resonance hybrid with a bond order of 1.5. In O2F2, the bond order is less than 2.0. Step 3: Since bond length is inversely proportional to bond order, O2 (bond order = 2.0) has the highest bond order and therefore the shortest (lowest) O-O bond length, corresponding to option (b).
