Statement I: Acid strength increases in the order given as 
.
Statement II : As the size of the elements 
, I increases down the group, the bond strength of 
and HI decreases and so the acid strength increases.
In the light of the above statements, choose the correct answer from the options given below.
Text Solution
Verified by ExpertsThe correct answer is:
B
In the modern periodic table, moving down the group as the size of halogen atom increases, the 
bond length also increases as a result the bond enthalpy decreases. Hence, The acidic strength also increases.
