Assertion: The experimentally determined carbon to oxygen bond length in carbon dioxide is 115 pm Reason: The lengths of a normal carbon to oxygen double bond (C=0) and carbon to oxygen triple bond (C ≡ 0) are 121 pm and 110 pm respectively. (A) If both assertion and reason are true and reason is the correct explanation of assertion (B) If both assertion and reason are true but reason is not the correct explanation of assertion (C) If assertion is true but reason is false (D) If both assertion and reason are false

In carbon dioxide, the carbon-oxygen bond lengths lie in between the values for (C=0) and (C ≡ O) bond lengths because carbon dioxide is a resonance hybrid of following structures: <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/84234350063b5e1b25fd7a7aa8873188-.png" />

Q. Assertion : The experimentally determined carbon to oxygen bond length in carbon dioxide is $115$ pm
Reason : The lengths of a normal carbon to oxygen double bond $(C = 0)$ and carbon to oxygen triple bond $(C \equiv 0)$ are $121$ pm and $110$ pm respectively.
