Given below are two statements : Statement (I): Experimentally determined oxygen-oxygen bond lengths in the O ₃ are found to be same and the bond length is greater than that of a O = 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 b
Options
- ABoth Statement I and Statement II are false
- BStatement I is false but Statement II is true
- CStatement I is true but Statement II is false
- DBoth Statement I and Statement II are true
Correct answer
C. Statement I is true but Statement II is false
Step-by-step solution
Bond length 1 Bond order Order of O - O bond length O = O < O ₃ < O - O Statement I is true. Lone pair-lone pair repulsion between O-atoms is not solely responsible for the correct order of O-O bond length. Bond order also should be considered. Statement II is false.
