I was just revising for my chem mock that's tomorrow and i was wondering why hydrogen bonding can't occur with chlorine..it's just as electronegative as Nitrogen, so what's the reason?
think chlorine doesn't have a lone pair of electron when bonded with hydrogen therefore due to chlorine not having a pair of lone pair it cannot bond or attract another H-CL atom.
Chlorine isn't as electronegative as Nitrogen, hence hydrogen bonding doesn't occur. Look at the period nitrogen is in and then look at chlorine. There is another shell for chlorine, so increased shielding for the outer electrons, and it has a larger atomic radius.

chlorine has three lone pairs just as fluorine does which does exhibit hydrogen bonding in HF
It is to do with the chlorine atom not being able to accept hydrogen bonds, it is however a reasonable donor.
