Question
Arrange the following in the order of property indicated for each set:
HF, HCl, HBr, HI - increasing acid strength
Solution
In the order of increasing acid strength in water (i.e., aqueous solution) HI is strongest acid while HF is the weakest acid.
This is because as moving down the group size increase and hence weaken the bond as a result more availability of hydrogen.
H-F<H-Cl<H-Br<H-I
