Question

explain why HCL is a gas and HF is a liquid

Answer 1

HCl a gas at room temperature and HF a liquid. ... Ans: Both HCl and HF are gases at room temperature. But HF has high boiling point than HCl because of the reason that in HF the strength of hydrogen bond is stronger than the strength of hydrogen bond in HCl.

Answer 2

Answer:

Due to greater electronegativity of F over Cl, F forms stronger H-bonds as compared to Cl. As a result, more energy is needed to break the H-bonds in HF than in HCl and hence the b.p. of HF is higher than that of HCl. Consequently, H-F is liquid while HCl is a gas at room temperature.
