View answer and explanation
Correct option: A
H−H>−C−H>−C−C−\mathrm{H}-\mathrm{H}>-\mathrm{C}-\mathrm{H}>-\mathrm{C}-\mathrm{C}-
Option A (H−H>−C−H>−C−C−\mathrm{H}-\mathrm{H}>-\mathrm{C}-\mathrm{H}>-\mathrm{C}-\mathrm{C}-) is correct because the H-H bond is the strongest, followed by C-H, and then C-C.
