- B \(-\mathrm{C}-\mathrm{C}->\mathrm{C}-\mathrm{H}>\mathrm{H}-\mathrm{H}\)
- C \(-\mathrm{C}-\mathrm{H}>-\mathrm{C}-\mathrm{C}->\mathrm{H}-\mathrm{H}\)
- D \(-\mathrm{C}-\mathrm{C}->\mathrm{H}-\mathrm{H}>-\mathrm{C}-\mathrm{H}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{H}-\mathrm{H}>-\mathrm{C}-\mathrm{H}>-\mathrm{C}-\mathrm{C}-\)
Step-by-step Solution
Detailed explanation
The decreasing order of bond dissociation energies of \(\mathrm{C}-\mathrm{C}, \mathrm{C}-\mathrm{H}\) and \(\mathrm{H}-\mathrm{H}\) bonds is as: \(\mathrm{H}-\mathrm{H}>-\mathrm{C}-\mathrm{H}>-\mathrm{C}-\mathrm{C}-\)
