NEET UG CHEMISTRY MCQ: CHEMICAL BONDING & MOLECULAR STRUCTURE

Option B ($1.22,1.15$ and $1.10 \mathop {\text{A}}\limits^ \circ$) is incorrect. The question asks for single, double, and triple bond lengths of carbon IN CARBON DIOXIDE. Carbon dioxide has two double bonds (O=C=O), so the question is flawed. However, if we interpret the question as asking for typical single, double, and triple carbon bond lengths, then the closest answer is B where 1.22 is a typical C=O double bond length, 1.15 is not a standard bond length, and 1.10 is a typical C≡C triple bond length. This question is poorly worded and has no correct answer. The question should be removed or reworded.
