Chlorine has an electronegativity of 3.16 on Pauling scale but the size of the chlorine atom is large (Van der Waals radius of chlorine is 175 pm) as a result it cannot strong hydrogen bond with smaller sized hydrogen(120 pm) but the size of nitrogen is comparatively (155 pm) thus it can form a strong hydrogen bond.(electronegativity 3.04)

If we consider between cl and N , Cl is bigger in size than that of N. That's why Cl can't make bond with H effectively. It will be an ionic bond. Cl has the 3p orbital and H has the 1s orbital. Besides N has 2p shell. So comparatively N can bond with H strongly.
