Question

HCL is a gas where as HF liquid at room temp ?

Priya G N · Accepted Answer

Hydrogen fluoride has a very strong permanent dipole, and so it
forms stronger permanent dipole-permanent dipole forces with other
HF molecules The strength of these permanent dipoles is caused by
the electronegativity of fluorine, being 4 0 and the highest
Therefore, HF molecules are very polar, i e they have a negative
end (fluorine end) and a positive end (hydrogen) This polarity
greatly attracts other HF molecules towards each Hydrogen bonding
is also present in between HF molecules, which creates large
attractions between a H atom of a HF molecule and an F atom of
other HF molecules These factors make HF a liquid at room
temperature

Hydrogen
chloride does not contain hydrogen bonding, despite chlorine having
the same electronegativity as nitrogen, oxygen and fluorine do The
reason for this is that a chlorine atom is much bigger than atoms
of oxygen, fluorine, or nitrogen, and so there is not as strong an
attraction between a chlorine atom of one HCl molecule and a
hydrogen atom of another HCl molecule These factors make HCl a gas
at room temperature
