In dilute aqueous solution HF is a weaker acid than HI, because

A

H-F bond energy is greater than HI bond energy

B

The hydration energy of `F^-` is higher than that of `I^-`

C

Of the presence of hydrogen bonds in HF

D

Fluorine is a stronger base as compared to iodine.

Text Solution

Verified by Experts

The correct Answer is:
A
HI is strongest acid because due to largest size of 1, the H-I bond is weakest and its bond dissociation energy is least so it breaks most readily and hence HI is the strongest acid. The order of acidic strength is HI gt HBr gt HCl gt HF
