Question

Hydrogen bonding exists in HF but now in HCL.Explain?

Answer 1

Hydrogen bonding exists in BOTH `H-F`, and `H-Cl`...

Explanation:

And we describe the polarization of the bond as `""^(+delta)H-X^(delta-)`; the dipole is stronger in `H-F` because fluorine is more electronegative than chlorine. The magnitude of intermolecular force is also expressed in the respective normal boiling points...`HF`, `19.5` `""^@C` versus ...`HCl`, `-85.5` `""^@C`.

Answer 2

Chlorine is a large atom, making the HCl have a high electronegativity measure, which is not significant enough to create a hydrogen bond.

Explanation:

Hydrogen bonds exist when hydrogen is attached to a fluorine, oxygen, or nitrogen atom. These are relatively small atoms that can attach to hydrogen to create a bond.
