MCQ
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 bond $( O = O )$ but more than that of a single bond $( O - O )$.
In the light of the above statements, choose the correct answer from the options given below:
  • Statement I is true but Statement II is false
  • B
    Both Statement I and Statement II are true
  • C
    Both Statement I and Statement II are false
  • D
    Statement I is false but Statement II is true

Answer

Correct option: A.
Statement I is true but Statement II is false
(A) Statement I is true but Statement II is false
Sol. Due to resonance bond length is identical in ozone. Therefore statement I is true and statement II is false
