Question

2
O H-F is a liquid but HCl is a gas
?​

Answer 1

Answer:

H-F is liquid while HCl is a gas at room temperature.

Answer 2

Due to the following reason, HF is liquid and HCl is a gas.

Explanation:

These are the following reasons:

• The Fluorine element is more electronegative than Chlorine, so Fluorine forms a stronger bond with hydrogen atoms which is an atom carrying a positive charge.
• Because of the stronger bonding of H and F, more energy will be required to break the bonds of hydrogen and fluorine.
• This energy makes HF's boiling point higher than the boiling point of HCl.
• That's why HF is a liquid and HCl is a gas at room temperature.
