Arrange the following bonds according to their average bond energies in descending order \(\mathrm{C}-\mathrm{Cl}, \mathrm{C}-\mathrm{Br}, \mathrm{C}-\mathrm{F}, \mathrm{C}-\mathrm{I}\)
- A \(\mathrm{C}-\mathrm{I}>\mathrm{C}-\mathrm{Br}>\mathrm{C}-\mathrm{C} 1>\mathrm{C}-\mathrm{F}\)
- B \(\mathrm{C}-\mathrm{Br}>\mathrm{C}-\mathrm{I}>\mathrm{C}-\mathrm{C} 1>\mathrm{C}-\mathrm{F}\)
- C \(\mathrm{C}-\mathrm{F}>\mathrm{C}-\mathrm{C} 1>\mathrm{C}-\mathrm{Br}>\mathrm{C}-\mathrm{I}\)
- D \(\mathrm{C}-\mathrm{C} 1>\mathrm{C}-\mathrm{Br}>\mathrm{C}-\mathrm{I}>\mathrm{C}-\mathrm{F}\)
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…
