Answer & Solution

Correct Answer

(C) \(\mathrm{C}-\mathrm{F}>\mathrm{C}-\mathrm{C} 1>\mathrm{C}-\mathrm{Br}>\mathrm{C}-\mathrm{I}\)

Step-by-step Solution

Detailed explanation

Bond length order in carbon halogen bonds are in the order of \(\mathrm{C}-\mathrm{F} < \mathrm{C}-\mathrm{C} 1 < \mathrm{C}-\mathrm{Br} < \mathrm{C}-\mathrm{I}\) Hence, Bond energy order…
