Arrange the following bonds according to their average bond energies in descending order: C − Cl, C — Chemical Bonding Chemistry Question

💡 Solution & Explanation

In C − F there is 2p − 2p overlapping involved, in C − Cl the overlapping involved is 2p − 3p whereas for C − Br and C − I the overlappings involved are 2p − 4p and 2p − 5p, respectively. The bond length for the various type of overlappings can be given as: 2p − 2p < 2p − 3p < 2p − 4p < 2p − 5p. As we know that Bond energy The order of bond energy comes out: C − F > C − Cl > C − Br > C − I
