JEE Mains · Chemistry · STD 11 - 4. Chemical bonding and molecular structure
Given below are two statements :
Statement (I): Experimentally determined oxygen-oxygen bond lengths in the \(\mathrm{O}_3\) are found to be same and the bond length is greater than that of a \(\mathrm{O}=\mathrm{O}\) (double bond) but less than that of a single \((O-O)\) bond.
Statement (II) : The strong lone pair-lone pair repulsion between oxygen atoms is solely responsible for the fact that the bond length in ozone is smaller than that of a double bond \((\mathrm{O}=\mathrm{O})\) but more than that of a single bond \((\mathrm{O}-\mathrm{O})\).
In the light of the above statements, choose the correct answer from the options given below :
- A Both Statement I and Statement II are false
- B Statement I is false but Statement II is true
- C Statement I is true but Statement II is false
- D Both Statement I and Statement II are true
Answer & Solution
Correct Answer
(C) Statement I is true but Statement II is false
Step-by-step Solution
Detailed explanation
Bond length \(\propto \frac{1}{\text { Bond order }}\) Order of \(\mathrm{O}-\mathrm{O}\) bond length \(\mathrm{O}=\mathrm{O} < \mathrm{O}_3 < \mathrm{O}-\mathrm{O}\) \(\therefore\) Statement \(I\) is true. Lone pair-lone pair repulsion between O-atoms is not solely responsible…
