Among the trihalides of nitrogen, which is the least basic ?

The pronounced change from non-metallic behaviour and also increase in the basicity of oxides from nitrogen to bismuth in group 15 is principally due to incresing size of the atoms. The ionisation potential of nitrogen is very high on account of its small size. However, ionisation potential decreases regularly on descending the group.
