textBond textenergy propto (1/ textBond length) As on moving down the group size increases so bond length increases hence bond energy decreases. Bond energy C-F>C- textCl>C- textBr>C-I

Q. Arrange the following bonds according to their average bond energies in descending order.

$C - Cl, C - Br, C - F, C - I$

$C - F > C - Cl > C - Br > C - I$

$C - I > C - Br > C - Cl > C - F$

$C - Br > C - I > C - Cl > C - F$

$C - Cl > C - Br > C - I > C - F$

$Bond energy \propto \frac{1}{Bond length}$

As on moving down the group size increases so bond length increases hence bond energy decreases.

Bond energy $C - F > C - Cl > C - Br > C - I$

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

C−F>C−Cl>C−Br>C−I

C−I>C−Br>C−Cl>C−F

C−Br>C−I>C−Cl>C−F

C−Cl>C−Br>C−I>C−F
