Single Choice

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

A$$C - Br > C - I > C - Cl > C - F$$
B$$C - F > C - Cl > C - Br > C - I$$
Correct Answer
C$$C - I > C - Br > C - Cl > C - F$$
D$$C - Cl > C - Br > C - I > C - F$$

Solution

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

Here in the above case, the bond strength is maximum for $$C-F$$ bond while least bond strength for $$C-I$$. Fluorine is the most electronegative.

Electronegativity order:

$$F > Cl > Br > I$$

Hence, option B is correct.
