Question

सामान्य ताप पर HF द्रव है तथा HCF गैस है क्यों

Answer 1

HF is liquid at room temperature as HF molecules are bonded by hydrogen bonding.

Explanation:

HF has high boiling point than HCl as HF molecules are bonded by strong hydrogen bonding between the hydrogen atom and a highly electronegative fluorine atom. Thus the molecules are closely packed.

In HCl, the hydrogen bonding cannot be formed in-spite of the presence of electronegative chlorine as the size of chlorine atom is too large, such that its electron density is too low to form hydrogen bonds. Thus the molecules are loosely packed and it is a gs.

Thus HF is a liquid and HCl is a gas.
