The correct sequence of bond enthalpy of ' 
bond is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
On moving down the group from F to I, the size of atom increases. Order of the size of
halogen atom is 
.
So, the bond length of 
bond also increases from F to I and hence, the bond enthalpy decreases from 
to I.
Correct order of bond length of 
bond is
.
Correct order of bond enthalpy is
.
