996Hydrogen bonds are attractions between a δ+ hydrogen on one molecule and a lone pair on a very
electronegative atom (N, O or F) on another molecule.
so for chlorine hydrogen bonding (dipole dipole interaction )is not effective
Chlorine is quite electronegative. So, why is hydrogen bond not present in HCl?
Thanx...

996no after flourine, oxygen followed by nitrogen is more electronegative ......here is the data for electonegativity:
fluorine = 4.0
oxygen = 3.5
nitrogen = 3.1
chlorine =3.0
it is because chlorine lies in next period it has 3 shells and also nuclear attractions is less in it.......

996337But, after Fluorine, Chlorine is the most electronegative. Chlorine is more electronegative than Oxygen, Nitrogen or Fluorine. Please correct me if I am wrong.
