Hi Saurav,

Nitrogen is more electronegative

electronegetivity of an element  depend on the oxidation state of the atoms, bonding situation and the amount of charge transferred to the bonding partner..

 

Nitrogen should be more electronegative, because:
1) NCl3 in H2O gives NH3 and HOCl, which proves that nitrogen is negatively charged because it attracts the positively charged hydrogen in H2O to form NH3 and chlorine combines with the negatively charged HO- radicals.
2) HNO3 is stronger that HClO3, though chlorine and nitrogen have the same oxidation state (+5)
pKa HNO3= -1.4
pKa HClO3= -1

3) According to Allen electronegativity scale, nitrogen has 3.07 and chlorine has 2.88
