QJEEM20Chf290: JEE Main 2020 Chemistry - Class 11 JEEM20Chf290 Solution: Arrange the following bonds according to their average bond…
Arrange the following bonds according to their average bond energies in descending order :
C–Cl, C–Br, C–F, C–I
C–Cl, C–Br, C–F, C–I
Multiple Choice Options
- A C–Br > C–I > C–Cl > C–F
- B C–Cl > C–Br > C–I > C–F
- C C–I > C–Br > C–Cl > C–F
- D C–F > C–Cl > C–Br > C–I
Step-by-Step Verified Solution
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
in the order of C – F < C – Cl < C – Br < C – I
Hence, Bond energy order
C – F > C – Cl > C – Br > C – I
