Answer 1

ANS.

The H−F bond requires more energy to break than the H−Cl bond.

SOLUTION

Acid strength depends on an ability to give a H+, which requires the breakage of the bond

The length of H−Cl bond is greater than the H−F bond

Bond strength∝1Bond length

Thus, the strength of H−F bond is greater than the H−Cl bond.

So, it is easy for HCl to give H+.

So, HCl is the strong acid.
