Easy MCQ +4 / -1 PYQ · JEE Mains 2020

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

  1. A C–Br > C–I > C–Cl > C–F
  2. B C–Cl > C–Br > C–I > C–F
  3. C C–I > C–Br > C–Cl > C–F
  4. D C–F > C–Cl > C–Br > C–I Correct answer

Solution

Bond length order in carbon halogen bonds are <br><br>in the order of C – F $&lt;$ C – Cl $&lt;$ C – Br $&lt;$ C – I <br><br>Hence, Bond energy order <br><br>C – F $&gt;$ C – Cl $&gt;$ C – Br $&gt;$ C – I
