Thus, the increasing order for bond dissociation energy among halogens is as follows: Bond dissociation enthalpy decreases as the bond distance increases from F2 to I2 due to increase in the size of the atom, on moving from F to I. F – F bond dissociation enthalpy is smaller then the Cl – Cl and even smaller than Br – Br. Cl2 Br2 F2 I2. Question: Rank The Following Molecules In Decreasing Bond Energy. asked Sep 20, 2016 in Chemistry by Book-Worm1. B.

Bond energy increase as you go down the periodic table, so I think it is I, Br2, Cl2 and F2. See the answer. This is due to the small atomic size of fluorine. The Bond dissociation energy of halogens decreases down the group as the size of the halogen is increases . Sorry but your professor is wrong. -1228 kJ 1228 kJ B. That's why the the bond dissociation enthalpy follows the order Cl2 >Br2>F2>I2. general-chemistry; 0 Answers. This is because, in fluorine molecule, two fluorine atoms are quite close together (i.e. Good luck Top Answer. Rank the following molecules in decreasing bond energy. F-F bond length is very short) due to full size of fluorine atoms. 0 0. mpingi. Find out more about how we use your information in our Privacy Policy and Cookie Policy.
