Question

Arrange the following bonds according to their average bond energies in descending order: C - Cl, C - Br, C - F, C - I (A) C - F > C - Cl > C - B r > C - I (B) C - Br > C - I > C - Cl > C - F (C) C - I > C - Br > C - Cl > C - F (D) C - Cl > C - Br > C - I > C - F

Bond length order in carbon halogen bonds are in the order of C - F < C - Cl < C - Br < C - I Hence, Bond energy order C - F > C - Cl > C - Br > C - I

Q. Arrange the following bonds according to their average bond energies in descending order:
$C - Cl, C - B r, C - F, C - I$

$C - F > C - Cl > C - B r > C - I$

$C - B r > C - I > C - Cl > C - F$

$C - I > C - B r > C - Cl > C - F$

$C - Cl > C - B r > C - I > C - F$

Bond length order in carbon halogen bonds are in the order of $C - F < C - Cl < C - B r < C - I$
Hence, Bond energy order
$C - F > C - Cl > C - B r > C - I$

Q. Arrange the following bonds according to their average bond energies in descending order: C−Cl,C−Br,C−F,C−I

C−F>C−Cl>C−Br>C−I

C−Br>C−I>C−Cl>C−F

C−I>C−Br>C−Cl>C−F

C−Cl>C−Br>C−I>C−F
