♣ Assertion: HF is weaker acid than HCl.

♥ Reason:

✍️ We know that,

Acid is the substance which gives hydronium ions ( H+ ) easily.

Now,

✍️ In Hydrochloric acid (HCl),

the bond strength between Hydrogen and Chlorine is weak as chlorine belongs to 3rd period which has more number of shells.

So, it can give H+ ions easily,

Hence,

it is strong acid.

Now,

✍️ In case of Hydrogen Fluoride ( HF),

Fluorine being the member of 2nd period has least number of shells, it attracts the Hydrogen atom more strongly,

thus,

it forms a strong between Hydrogen and Fluorine atoms.

So, it is difficult to liberate H+ ions easily,

Hence,

it is a weak acid.
