Question

Hcl is a gas while HF is a liquid at room temperature, it is due to,

Answer 1

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...

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.

The Intermolecular hydrogen bonding is present in HF molecule than in other hydrogen halides. HCl does not have hydrogen bonding. Hence HF is a liquid at room temperature and HCI  is a gas
