7.36 Arrange the following in the order of property indicated for each set:
(i) ,
,
,
- increasing bond dissociation enthalpy.
Bond dissociation energy usually decreases as we move down in a group, Bond dissociation energy usually decreases as the atomic size increases. whereas, the bond dissociation energy of is lower than that of
and
. This is due to the small atomic size of fluorine. hence,
