Although chlorine has the same electronegativity as nitrogen, it does not form hydrogen bonding....

Although chlorine and oxygen have nearly same electronegativity yet only oxygen from hydrogen bond explain it ?

Why nitrogen does not form penthalides?

Acetylene does not form hydrogen bond because :

Nitrogen does not form complexes because

Although Chlorine (EN = 3.2) is more electronegative than Nitrogen (EN = 3.0) , yet chlorine does not form hydrogen bond while nitrogen does. Give reason. (Ans: larger atomic size of Cl ).
