Increasing order of carbon-carbon bond length for the following is
- A \(C < B < A < D\)
- B \(B < C < A < D\)
- C \(D < C < A < B\)
- D \(B < A < C < D\)
Answer & Solution
Correct Answer
(D) \(B < A < C < D\)
Step-by-step Solution
Detailed explanation
In \(\mathrm{C}_{2} \mathrm{H}_{6}\), carbon-carbon bond is single (1.54 А). In \(\mathrm{C}_{6} \mathrm{H}_{6}\), carbon-carbon bond is partially double (1.39 A)
In \(\mathrm{C}_{2} \mathrm{H}_{4}\), carbon-carbon bond is double \((1.34 Å)\)
In \(\mathrm{C}_{2} \mathrm{H}_{2}\), carbon-carbon bond is triple \((1.10 Å)\)
In \(\mathrm{C}_{2} \mathrm{H}_{4}\), carbon-carbon bond is double \((1.34 Å)\)
In \(\mathrm{C}_{2} \mathrm{H}_{2}\), carbon-carbon bond is triple \((1.10 Å)\)
